Factors used: level-wide ROK factors (no league-specific row for this league/era). Park (home-season share, regressed): HR 89, 1B 97, 2B 99, 3B 100, K 98, BB 98 — applied at half strength.

Result: wOBA .341 → .219; ISO .174 → .111; BABIP .354 → .263. 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).
