0.0×
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.
0
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.
59
Appearances ?Total times this batter has appeared in the model's daily scored pool this season.
11
Top-50 Days ?Number of days this batter ranked in the top 50 on the slate. Top-50 is the model's primary recommendation zone.

12%
Catch Rate ?Percentage of this batter's HRs that occurred when the model had them ranked in the top 50. Higher = model does a good job timing this batter. 60%+ is excellent.
