How the minor-league lines were translated

One row per minor-league stint. Open a row to see each step: the raw rate, the park adjustment, the league/level factor, the age adjustment (hitters) and the resulting MLE rate. Factors are the same ones listed on the MLE Factors page.

Factors used: level-wide AAA factors (no league-specific row for this league/era). Park (home-season share, regressed): HR 103, 1B 107, 2B 110, 3B 84, K 98, BB 92 — applied at half strength. Age: age 46 vs a level average of 27.2 → −6.0% on BB/HBP/hit rates (18.8 yr older than average).

Result: wOBA .275 → .215; ISO .024 → .019; BABIP .258 → .215. 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).
