Factors used: level-wide AAA factors (no league-specific row for this league/era). Park (home-season share, regressed): HR 80, 1B 95, 2B 92, 3B 130, K 98, BB 109 — applied at half strength.

Result: wOBA .295 → .216; ISO .192 → .142; BABIP .273 → .229. 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).
