What Is Hit Factor?
Hit factor is the scoring method used in IPSC and USPSA practical shooting competitions. It measures a shooter's performance as points per second — rewarding both speed and accuracy.
How Hit Factor Is Calculated
Hit Factor = Total Points ÷ Time (seconds)
For example, if you score 120 points on a stage in 15 seconds, your hit factor is 120 ÷ 15 = 8.0000.
The shooter with the highest hit factor on a stage gets 100% of the available stage points. Everyone else is scored as a percentage of that top hit factor. This is sometimes called "Comstock" scoring.
Point Values by Hit Zone
In USPSA, targets have scoring zones that award different point values. The exact values depend on the power factor (Major or Minor):
| Zone | Minor | Major |
|---|---|---|
| A | 5 points | 5 points |
| C | 3 points | 4 points |
| D | 1 point | 2 points |
| Miss (M) | −10 points | −10 points |
Penalties (like hitting a no-shoot target or failing to engage a target) also deduct points, which directly lowers your hit factor.
Why Hit Factor Matters
Hit factor captures the core challenge of practical shooting: balancing speed and accuracy. Going faster improves your hit factor, but only if you maintain your points. Shooting all alphas is great, but not if it takes too long.
This creates strategic decisions on every stage. Should you take an extra split-second to aim for the A-zone, or accept a C-hit and move on? The answer depends on how much time that extra aim costs versus the points gained — and that's exactly what hit factor measures.
What Is a Good Hit Factor?
Hit factor varies significantly by stage design — a short, close-range stage will produce much higher hit factors than a long-range precision stage. Here are rough benchmarks for USPSA:
- 2–4 HF: Typical for long or accuracy-heavy stages
- 5–7 HF: Common on medium stages with a mix of targets
- 8–12 HF: Fast, close-range stages or speed shoots
- 12+ HF: Very short stages with close, easy targets
Rather than comparing raw hit factors between stages, it's more useful to look at your stage percentage— how your hit factor compares to the best shooter on that stage. That's exactly what HitFactor Lens helps you analyze.
Other Scoring Methods
While hit factor (Comstock scoring) is the most common, practical shooting also uses other scoring methods:
- Virginia Count: Fixed number of rounds — time is the tiebreaker, not part of the score formula. Points alone determine placement.
- Fixed Time:A set time limit where only points matter. Finishing early doesn't help.
- Chrono (Chronograph): Not a competitive stage — used to verify that ammunition meets the minimum power factor requirements.
