Context only. Streaks and hot or cold labels don't move a projection: in our tests recent results didn't predict the next two weeks better than the season.

A season-level read, blending this season with last, shrunk toward league where the sample is thin.

Jahmai Jones · percentile ranksvs 304 hitters on the slate with 60+ PA · last 90 days

Right is always better for the hitter: K% and whiff are ranked low-to-high. Context only; a percentile isn't a projection.

Hits in 2 of 3 settled games; the projections added up to 1.6. A handful of games says little about the model on its own.

One player's handful of games says little about the model; the market-level record is on the record. A game he never batted in is void, not a miss.
