Rolling form against the season-to-date baseline, game by game. Computed with the same windowed primitives the models backtest with, gates included: the shaded band is where the window had no real sample yet, so no value is drawn there rather than a guess.
ERA
WHIP
Each outcome is fit as logit P = μ + βbatter + πpitcher across every plate appearance in the season, so hitter and pitcher skill are solved together rather than one being assumed. The adjusted column is this player against a league-average opponent; the run value is that rate priced by its wOBA weight (a walk is worth .690 runs, a home run 2.015), and those values sum to the adjusted wOBA above.

Regressed is how many plate appearances of league-average performance are blended in before a rate is believed — estimated from the spread of the league itself, not chosen. Strikeout rate separates hitters quickly and is barely touched; doubles are mostly noise and are pulled hard toward average. It is why a hot 30-PA cameo does not top this list.
The opponent effect is usually small over a full season, and that is a finding rather than a shortcoming: individual pitchers differ enormously (wOBA allowed spans roughly .263 to .342), but across hundreds of plate appearances almost everyone faces a near-representative sample. The adjustment moves part-time players far more than regulars.

Aggregated from the per-game rows, so a season total always equals the sum of the games behind it. Seasons before the coverage window are absent rather than partial.
