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: league row International League. Park (home-season share, regressed): HR 104, 1B 98, 2B 84, 3B 130, K 91, BB 103 — applied at half strength. Age: age 39 vs a level average of 27.2 → −6.0% on BB/HBP/hit rates (11.8 yr older than average).

Result: wOBA .450 → .298; ISO .462 → .293; BABIP .200 → .155. 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).
