Hit factor on the track
On the track, hit factor summarizes efficiency: how many valid points you scored per second. Zones and penalties are included in the points count; time includes route. A high HF with lots of M can be deceiving — so always cross with hits and PROC. Dedicated page: /o-que-e-hit-factor-ipsc.
PSBL in the entire test
PSBL compares points obtained with maximum possible points (zones × shots). Useful in comparison when you want “how much of the race I enjoyed” regardless of the pace. Conceptual documentation: docs/psbl.md and docs/hitfactor.md.
Power factor and zone scoring
Major/minor change the weight of C and D — the same series of shots generates different hit factors. See /factor-major-vs-minor-ipsc. Hits and penalties: /hits-and-penalties-ipsc.
From theory to calculator
On the website, POST /calculo_factor helps with power factor exercises. The comparison in /comparacao displays PSBL in the summary tables. In the hub, charts by lane show HF side by side.
Where to calculate and compare
Calculators and graphs in the test hub; public comparison in /comparacao. For combined theory: /como-calcular-combinado-ipsc.
PSBL: what it is and calculation example
PSBL (Percentage of Possible Points) measures the athlete's performance compared to the maximum in the event. Formula: total points ÷ (number of targets × 5). If you scored 900 out of 1000 possible points, your PSBL is 90%. It is a complement to the hit factor (/o-que-e-hit-factor-ipsc), which considers time, and to hits and penalties (/hits-e-penalties-ipsc).
