Observed from monthly USCF rating records since December 1, 2025. These set changes are not confirmed new registrations, membership expirations, or renewals: records can also enter or leave because of source coverage, geography, or eligibility filters. “First observed active” means no earlier active snapshot is retained for that member in South Dakota, and changes occurring between snapshots may not appear.
