1. Countywide historical model — distinct events versus division records

The September 20, 2026 AIUSSSA - HVIOG 9-20-2026.csv contains 20,305 statewide division rows. This county analysis filters the original County field to exactly “Sequoyah,” yielding 286 rows and 118 distinct event identifiers (the numeric division suffix is removed from TournamentID and the resulting base identifier is paired with Seasonid). These are historic source listings, which can include leagues and canceled events; an identifier is not independent proof that games occurred.

Concession margins: 30%, 50% and 70% are illustrative contribution-margin scenarios applied to gross concessions; operating expenses, labor, taxes, inventory and contractual revenue splits have not been verified. The source’s TotalEventNet is a different modeled field and is not a concession net or public-sector profit figure.

2. Municipality and facility ledger — disjoint groups that reconcile

For event-level consistency, the four 2024 division rows of source event 14351 are kept together in one “Sallisaw + Muldrow” multi-location group, including two rows displaying only the Sallisaw Sports Complex. Likewise, all five 2014 rows displaying the complex are quarantined as a pre-opening label verification group. Thus no event is counted twice when adding groups to county totals.

2A. Municipality grouping

Gross revenue scenarios

Concession contribution margin sensitivity

Games, umpiring, sanctions

2B. Facility and unresolved site grouping

The supplemental exact-label CSV retains the original four facility strings. Those literal labels show the same 2024 event in three different groups, so their distinct-event columns do not sum to the county total. The four event-disjoint groups displayed above do reconcile at row, team and dollar levels.

3. Countywide modeled economic impact — not audited incremental benefit

Source-column reconciliation: Σ DayImpact = $212,315; Σ OvernightImpact = $102,306; Σ TotalEconomicImpactPerEvent = $314,621. The sum of the first two matches the third exactly across 286 division records. Despite “PerEvent” in its name, TotalEconomicImpactPerEvent exists on every division row and is not one independent estimate for each of the 118 distinct events.

3A. Municipality reconciliation

3B. Facility and unresolved attribution reconciliation

3C. Exact row-level formulas and actual source variations

DayImpact = TeamsEntered × DayTripRate × DayStay; OvernightImpact = TeamsEntered × NightTripRate × OverNightStay; TotalEconomicImpactPerEvent = DayImpact + OvernightImpact. Both rates and stay multipliers are dataset assumptions, not sourced customer expenditures or verified travel nights. In these 286 rows, DayTripRate varies between $25 and $85; NightTripRate between $0 and $289; DayStay takes values 1, 2, 14, 15, 27 or 33; and OverNightStay takes 0, 1 or 2. Our comparison retained these row-level variations rather than imposing uniform statewide rates.

Do not add: modeled entry fees, gate, gross concessions, net-concession scenarios or the source's TotalEventNet to $314,621. Gate, entry and concessions may already represent overlapping local visitor spending, and source visitor estimates may include local resident purchases. A defensible incremental study would require survey-derived origin, counterfactual activity, geographic leakage, displaced spending, tax jurisdiction, actual receipts and independently supported multipliers.

4. A public-record test: the 2014 facility label predates the documented opening

The Sallisaw municipal Sports Complex profile states that Sallisaw Sports Complex opened in May 2016, occupies 130 acres, has baseball/softball fields with concessions, and is operated by Sallisaw Youth League under contract with Sallisaw Municipal Authority. Yet five 2014 source division rows for the “Sallisaw League” event, 16316-1 through 16316-5, name “Sallisaw Sports Complex” at 1300 Steve Davis Parkway. These five rows total 28 team entries, $92,400 modeled gate, $46,200 modeled concessions and $23,100 modeled visitor spending.

This date inconsistency does not demonstrate improper conduct or an actual transaction. It may reflect a retrospective facility-name update, legacy tournament migration, temporary facilities, a data-entry error or a different historical location. The exact 2014 field, organizer and contract records must be checked before associating the model with the new complex. Moreover, ten April 2016 source records precede the May formal opening, including an April “Soft Opening” listing; these are a separate documentation question, not proof that pre-opening practice was unauthorized.

Historical facility migration: the McGee Complex source label appears in 2012–2015, while most “Sallisaw Sports Complex” rows occur after 2016. The Sallisaw Chamber: softball fields on McGee Drive independently identifies city softball fields on McGee Drive, but that public reference by itself does not verify the source's street address or title for every 2012–2015 event. This is an opportunity for facility-to-record crosswalking, not grounds for assigning past McGee activity to the newer facility.

5. The cancellation, rainout and league-duration sensitivity test

31 division rows / 11 event IDs have titles suggesting cancellation, rainout or similar status. Even so, their source financial columns aggregate $38,765 entry fees, $21,000 gate, $10,500 concessions, and $19,482 modeled visitor spending. Those are embedded historical model values, not evidence that canceled events collected those amounts. The records-request checklist prioritizes refunds, cancellation decisions, transaction logs and bracket results.

The county model also includes leagues with TotalEventDays of 14, 15, 27 or 33. The row-level gate equation in the source is TotalEventGate = TotalGateAdmissionFee × TotalEventDays, with TotalGateAdmissionFee = DailyFans × DailyAdmissionFee. The exact source rows here assume $5 daily admission and a gross concession value equal to 50% of modeled gate. These simplifying assumptions should not be mistaken for turnstile counts, admissions policy, concession contracts, paid attendance or actual 33-day tourism.

6. Reproducible field dictionary, equations and control checks

County inclusion: filter County == 'Sequoyah' in the September 20 CSV; all 286 source records have a single Sequoyah county label. A separately generated county crosswalk (verified to match the 65 original CSV columns on all 20,305 statewide rows) was used only to identify candidates for primary-site review. The 2023 two-row Muskogee/Sequoyah listing is not included without a verified primary facility.

QC results: all 286 rows satisfy both source economic-impact formulas exactly; modeled gross concession equals one-half of modeled gate in all 286 rows; modeled umpire costs equal source slots times $40; and the disjoint group totals reconcile to the county for every displayed additive metric. The 118 distinct events are nonadditive if counting duplicated event IDs under literal source facility names, hence the separate four-group control ledger.

7. Primary facility county test — do not transfer mixed-county activity without proof

Two additional division rows for a March 26, 2023 event titled “Sallisaw One Day Event – After The Storm” list both Love Hatbox Field in Muskogee County and Sallisaw Sports Complex in Sequoyah County. They total 18 team entries and $1,530 modeled visitor spending. Their source County value is “Muskogee, Sequoyah.” They are excluded from the 286-row Sequoyah headline until a bracket, director schedule, permit or other primary-facility evidence identifies the actual primary site. Listing Muskogee first is not proof of primary host.

Event 14351 is different: all possible listed facilities are in Sequoyah County, so the four divisions count toward the county but remain an unresolved municipality/facility ownership group. The parent county assignment and the finer facility allocation answer different questions.

8. Public finance: construction, operational custody, annual audits

The Sports Complex is relevant to public investment because the City confirms a sales-tax-backed construction financing structure and an operating contract with the youth league. Municipal spending, authority agreements, tournament operator activity and independent team registration receipts should not be conflated. The City of Sallisaw government, finance, records responsibilities identifies the finance department's duties and the City Clerk's records role; City of Sallisaw budget information lists adopted budget materials.

The City publishes City of Sallisaw FY2025 independently audited financial statements (PDF) signed November 26, 2025. The FY2025 auditor expressed an unmodified opinion on the financial statements. The schedule at report pages 63–64 reports no current-year financial-statement or federal-award findings. This is an important safeguard: those results do not audit or substantiate the Hidden Valley event-level gate, entry and concession models, nor do they resolve source event cancellation or venue anomalies. The audit includes a Youth & Recreation Fund and Sallisaw Municipal Authority schedules that can guide a more precise ledger request.

For county-government spending, the Sequoyah County Clerk: audits/financial report access describes the county clerk's purchasing and accounting roles, and the Oklahoma State Auditor / Digital Prairie Sequoyah County audit, FY2022 provides an Oklahoma State Auditor & Inspector Sequoyah County FY2022 audit archive reference. That is a county-government report, separate from City and Municipal Authority accounting; we do not attribute tournament collections or specific audit findings to the County without vouchers or a directly relevant finding.

9. Organizations, cooperation and the community-access test

The City names Sallisaw Youth League as contractual complex operator. Tournament director or organization names appear in the research dataset as historical listing fields; inclusion does not establish who received each payment, who owns a property, who employed officials or who owes statutory duties. An operator, municipality, school district, tournament sanctioning body and county agency can have different legal and financial roles.

A constructive collaborative review should invite Sallisaw City management, Sallisaw Municipal Authority, the Youth League, school administrators where involved, Sequoyah County officials and community groups to document: accessible dates for recreational play; resident team fee schedules; youth-participation subsidies; maintenance response times; school field-use terms; ADA accessibility; public safety; operator insurance; and whether public capital led to measurable and broadly shared benefits. A claimed economic impact alone does not settle those questions.

10. District attorney limits, court cases and case-outcome standards

The official Oklahoma District Attorneys Council — District 27 identifies District Attorney Jack Thorp, District 27, with responsibility for Adair, Cherokee, Sequoyah and Wagoner counties. That state district boundary is not county property jurisdiction, tribal criminal jurisdiction or civil contract authority. Federal, tribal and state jurisdictional rules can differ, and no prosecutorial power or alleged wrongdoing should be inferred from a dataset label.

Official court docket/outcome register for this installment: No directly relevant, authenticated Sequoyah County sports-complex litigation disposition has been established in this research. Therefore no case number, party allegation, lawsuit outcome or liability finding is asserted. The public may consult the OSCN official docket search and court clerk / online county records, verify filings and judgments, and preserve distinctions among a complaint, pending motion, judicial holding, dismissal and final judgment.

Separate statewide legal example (not a Sallisaw case): the Oklahoma Supreme Court in McKesson Corp. v. Campbell, 2022 OK 6 (Jan. 18, 2022), issued writs of prohibition and mandamus in a dispute about obtaining confidential prescription-monitoring data in civil discovery; confidentiality under the Open Records Act was not automatically a civil-discovery privilege. This decision does not require disclosure of every confidential public record or establish any youth-sports wrongdoing. It illustrates why any legal precedent's actual holding and outcome must be distinguished from the underlying allegations.

11. Targeted Oklahoma Open Records Act requests — proposed, not submitted

The Oklahoma Open Records Act statutory section index identifies the governing Open Records Act, 51 O.S. §§ 24A.1 et seq.; the Oklahoma Attorney General Open Records Act guidance explains records-access principles. Sallisaw directs requesters to its City Clerk; the City of Sallisaw government, finance, records responsibilities provides City Clerk and finance pathways. Requests below are research priorities only; no request was submitted or acknowledged during preparation of this article.

City of Sallisaw / Municipal Authority

1. 2014–2016 site reservation calendars, field assignments, construction and provisional-use documents, including April 2016 soft-opening records and any March–June 2014 event venue documents.
2. Sports Complex parcel deeds, plats, title instruments, bond resolution, trust indenture, construction contract change orders, ½-cent sales-tax receipts, actual bond principal/interest payment ledger and retirement confirmation.
3. Executed Sallisaw Youth League / Municipal Authority operating agreements and amendments (2009–2026), concession rights, gate staffing/collection policy, rental schedules, insurance, audits and reimbursements.
4. Year-by-year parks/authority revenues and expenses by facility for maintenance, capital improvements, utilities, admissions, food concession contracts and reimbursement of event-related costs.
5. Specific 2014 source event 16316 venue and league records; April 2016 “Soft Opening” event 5377 documents; and March 2024 event 14351 field allocation and school use authorization.

County, school and operator follow-up

1. Sequoyah County Clerk: any county appropriation, project agreement, lease, deed or audit record specific to these facility parcels or jointly funded recreation programs.
2. Relevant school authorities: 2024 Muldrow High School/Sallisaw High School field-use approvals, which party collected fees, and any liability/maintenance agreements.
3. Organizers / sanction bodies: original event records, bracket results, attendance evidence, cancellation/refund history, first/last games and per-division primary site.

Request status as of October 25, 2026: Research-only / not submitted. Subsequent request numbers, confirmations, fees, productions, exemptions and dates must be documented before changing status.

12. Right of response, careful corrections and evidence tiers

Before assigning legal ownership, financial receipt custody or operational liability, written explanations should be sought from the City, its Municipal Authority, Sallisaw Youth League and any relevant school or private rights-holder. A response can document that a historical venue label reflects data migration or that a modeled canceled event collected no gate receipts. The article must be corrected when original records change an attribution.

Evidence tiers: verified = contemporaneous municipal contract, deeds, original approved venue schedule, authenticated accounting or official judgment; dataset corroborated = September 20 row and crosswalk consistent but primary host not externally established; unresolved = conflicting historical date, multiple facilities, mixed counties, cancellation status or unverified ownership. The present dataset is not an enforcement finding. Log changes with date, source, before/after figure and treatment of previous versions.

13. Source register — municipal, county, state and court records

Dataset: user-supplied authoritative AIUSSSA - HVIOG 9-20-2026.csv, 20,305 rows, 65 original source columns, analyzed for exact source-coded county rows; and the 2026 user-generated county crosswalk for candidate county screening only. Dataset rates, admissions and modeled spending are not government findings.

Method limits: source links establish only the cited proposition; a municipal program may have changed since a historical event. The statewide court decision above is a legal illustration, not a Sequoyah controversy. The county's 2022 audit does not stand in for City FY2025 auditing. A “PerEvent” field is not a distinct event count. No commercial touristic impact multiplier or tax-revenue conversion has been applied.
