Run T-0022 passed

· Evidence: SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds; then the test stops.

Hypothesis

Coherent should make stronger moves under tournament time controls because phase-aware soft time limits save clock in stable positions and let unstable positions search longer within a reserved hard limit.

Predecessor set to: T-0022

Point estimate with the reported 95-percent half-width, per stage. The dashed line is zero. Estimates from a stopped sequential test are biased by the stopping rule; the interval is nominal.
