By season
Announced gate — tickets distributed, which is the figure every reference publishes and is not the same as people through the turnstile. A game the feed reports no gate for is left out rather than counted as empty. Seasons before attendance was carried into the lake are absent from the trend rather than shown as zero.

By season
Regulation games only, in minutes. 193 minutes this season.
Elapsed time from first pitch to final out. The feed does not itemise delays, so a rain delay is inside these numbers with no way to subtract it. Games called early are excluded — five innings in ninety-three minutes is not a short game — but they still count in attendance, because the crowd turned up.
Boston Red Sox are 92-70, a .568 win rate, while their +80 run differential implies .546. That is about 4 wins ahead of it, usually a mix of bullpen sequencing and one-run luck.
