Guide. Resumo (pt-BR): **Hit factor e PSBL: as métricas que organizam o tiro prático**. Hit factor e PSBL no tiro prático: como calcular pontos ÷ tempo, como a pista vira pontos de stage e como comparar atletas na prova inteira. Guia e calculadora.

[Read article](https://scoring.services/pages/hit-factor.md) ## Quick actions - [Combined](https://scoring.services/pages/overall-vs-combined.md): Aggregation of all stages. - [Comparative](https://scoring.services/pages/comparative-graphs.md): HF per stage between athletes. - [IPSC Guide](https://scoring.services/pages/ipsc-guide.md): Technical index by topic. ## What you get on this page - Hit factor = points ÷ time on stage. - PSBL = percentage of possible points. - Joint use in comparative and PSBL tables. ## Quick summary - Hit factor = points ÷ time on stage. - PSBL = percentage of possible points. - Joint use in comparative and PSBL tables. - See the sections below and the shortcuts to apply to your match or broadcast. ## Hit factor on the stage On the stage, hit factor summarizes efficiency: how many valid points you scored per second. Zones and penalties are included in the points count; time includes movement. A high HF with lots of M can be deceiving — so always cross with hits and PROC. Dedicated page: /pages/hit-factor. ## PSBL in the entire match PSBL compares points obtained with maximum possible points (zones × shots). Useful in comparison when you want “how much of the match I enjoyed” regardless of the pace. Conceptual documentation: https://scoring.services/docs/scoring.md and https://scoring.services/docs/scoring.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 /pages/major-minor-scoring. Hits and penalties: /pages/scoring-penalties. ## From theory to calculator On the website, POST /calculo_factor helps with power factor exercises. The comparison in /tools 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 match hub; public comparison in /tools. For combined theory: /pages/overall-vs-combined. ## 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 (/pages/hit-factor), which considers time, and to hits and penalties (/pages/scoring-penalties). ## Frequently asked questions ### Is high HF always good? On the stage, yes in relation to others on the same stage; In the match, also analyze consistency between stages. ### PSBL and percentage in the division? PSBL measures the use of possible points; percentage in the division positions you vs the best in the division in the combined — complementary. ### Where to train reading? Open /tools after an imported match and read summary tables + graphs. ### Are PSBL and hit factor the same thing? Hit factor is points/time per stage. PSBL (% of possible points) summarizes efficiency relative to the stage's maximum. IPSC details at /pages/hit-factor. ### What is PSBL and how is it calculated? PSBL (Percentage of Possible Points) is the percentage of possible points that the athlete achieved in the match. It is calculated by dividing the athlete's total points by the maximum possible (number of targets × 5 points). Example: 900 points in a match out of 1000 possible = PSBL of 90%. ## Related guides - [IPSC combined results](https://scoring.services/pages/combined-results.md) - [Practical Shooting Statistics: From Raw Number to Training Decision](https://scoring.services/pages/shooting-stats.md) ## Reference for agents - [Pontuação IPSC, overall e combinado](https://scoring.services/docs/scoring.md) - [llms.txt](https://scoring.services/llms.txt) - [llms-full.txt](https://scoring.services/llms-full.txt) Cite match numbers as imported analysis data, not federation homologation.
