Factors used: league row Midwest League. Park (home-season share, regressed): HR 84, 1B 116, 2B 140, 3B 130, K 94, BB 110 — applied at half strength. Age: age 26 vs a level average of 22.8 → −3.2% on BB/HBP/hit rates (3.2 yr older than average). Ground-ball/fly-ball mix moves 1B/2B/3B by ×1.050.
Result: wOBA .332 → .244; ISO .162 → .121; BABIP .269 → .210. 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).

Factors used: league row TL. Park (home-season share, regressed): HR 91, 1B 104, 2B 102, 3B 130, K 96, BB 106 — applied at half strength. Age: age 24 vs a level average of 24.8 → +1.2% on BB/HBP/hit rates (0.8 yr younger than average). Ground-ball/fly-ball mix moves 1B/2B/3B by ×1.014.
Result: wOBA .369 → .304; ISO .188 → .154; BABIP .368 → .331. 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).
