Management checks

  • - Recent load = yesterday + 65% of two days ago + 35% of three days ago.
  • - Safe cap = today max - fatigue score x 0.45, never below zero.
  • - Coverage innings = planned pitches / expected pitches per inning.

How bullpen availability is estimated

The planner weights pitch counts from the last three days, subtracts rest credit, compares today's plan with a role-based pitch cap, and translates planned pitches into inning coverage.

Usage notes

  • Recent load = yesterday + 65% of two days ago + 35% of three days ago.
  • Safe cap = today max - fatigue score x 0.45, never below zero.
  • Coverage innings = planned pitches / expected pitches per inning.

Frequently asked questions

Is this a medical workload rule?expand_more

No. It is a planning estimate for coaches and scorekeepers. Always defer to player health, coaching judgment, and league rules.

Why separate planned pitches from safe capacity?expand_more

Safe capacity shows what the bullpen might be able to cover, while planned pitches show the actual usage you are assigning today.
