Factors used: league row International League. Park (home-season share, regressed): HR 96, 1B 100, 2B 108, 3B 130, K 95, BB 111 — applied at half strength. Age: age 36 vs a level average of 27.2 → −6.0% on BB/HBP/hit rates (8.8 yr older than average).

Result: wOBA .154 → .112; ISO .048 → .032; BABIP .154 → .125. Both wOBAs use the same linear weights, so the change is the translation alone. The MLE line is not regressed to the mean — regression happens later, when seasons are blended into a projection (how).
