Estimate a pitching session’s internal workload from pitch count and average effort, with added weight for high-intent pitches. The result is a transparent tracking index for comparing your own bullpens, live sessions, and outings—not a medical limit or universal pitch-count rule.
Session load = total pitches × (effort ÷ 100)² + high-intent pitches × 0.5. Seven-day load adds the prior six-day load.
Effort is squared so higher-intensity work contributes disproportionately. The high-intent term distinguishes sessions with many near-maximal pitches from easier command work.
This index is not an injury predictor and does not replace age-specific rules, organizational policies, or medical guidance.
Seventy-five pitches at 85% average effort with 20 high-intent pitches produce 64.2 session load units. With 180 prior units, the seven-day total is 244.2.
Yes. Enter them as a subset; the calculator adds extra weight for their intensity.
Squaring makes an increase near maximal effort contribute more than the same increase at low effort.
No. It is a personal tracking index and does not override applicable rules or professional guidance.
Choose a consistent policy. Include them if you want the index to reflect all throwing and do so every time.
No. Workload is one piece of context and cannot produce an individual injury probability.
