Combination of two ideas: Apply bonus for the prior CMH that caused a fail low. Balance Stats: CMH and History bonuses are updated differently. This eliminates the "fudge" factor weight when scoring moves. Also eliminated discontinuity in the gravity history stat formula. (i.e. stat scores will no longer inverse when depth exceeds 22) STC: LLR: 2.96 (-2.94,2.94) [0.00,5.00] Total: 21802 W: 4107 L: 3887 D: 13808 LTC: LLR: 2.96 (-2.94,2.94) [0.00,5.00] Total: 46036 W: 7046 L: 6756 D: 32234 Bench: 7677367
