Dueness ?Games since last HR ÷ typical cadence. 1.0× = right on schedule. Above 1.0× = overdue relative to their own baseline. 1.5×+ = significantly overdue.
1
Games Since HR ?How many games (appearances in the scored pool) since this batter's last home run.
8
Typical Cadence ?Median number of games between home runs this season. Uses median (not average) for robustness against streaky outliers. Requires 3+ HRs to establish a baseline.
Games between HRs ?Each bar = the number of games between consecutive HRs. The final highlighted bar is the current gap (still open). Bars above the typical cadence are colored differently.
