What is hit factor — and why it matters

Hit factor is USPSA's stage score: your points minus penalties, divided by your time — points per second. A 90-point run in 15.00 seconds is a 6.0000 hit factor. It's the single number that decides every USPSA stage, and it's why the sport is a balancing act: shooting more accurately raises the top of the fraction, shooting faster shrinks the bottom, and your job is to find the mix that makes the whole number biggest.

What counts as points

USPSA targets score by zone: an A hit is 5 points for everyone. C and D hits depend on your power factor — the "punch" of your ammunition. Shooting major, a C is 4 and a D is 2; shooting minor, a C is 3 and a D is 1. (That's the whole reason power factor exists: major ammo recoils more, so its off-center hits cost less.) Penalties subtract: a miss is −10, a hit on a no-shoot is −10, a procedural is −10. All three are twice the value of an A hit, which is where the number comes from — rule 9.4 sets the miss and the no-shoot, rule 10.1.2 sets the procedural, and Appendix B1 is what makes an A worth 5. A stage score can't go below zero.

A worked example

Say a stage has 18 required hits and you shoot 12 A's, 5 C's, and 1 D in 14.50 seconds, clean, at major:

• Points: 12×5 + 5×4 + 1×2 = 82 points
• Hit factor: 82 ÷ 14.50 = 5.6552

The same run at minor scores 12×5 + 5×3 + 1×1 = 76 points, for a 5.2414 hit factor — identical shooting, a different score, purely from how your ammo scores the C's and D's.

What does DVC mean?

DVC stands for Diligentia, Vis, Celeritas — which USPSA renders as accuracy, power and speed. The letters are on the USPSA logo and on half the stickers at any match, and it would be easy to file them under decoration; Latin on a sticker usually is. But the rulebook means it. Its second Principle of Practical Shooting reads: “Accuracy, power and speed are the equivalent elements of practical shooting and practical competition must be conducted in such a way as to evaluate these elements equally.” (USPSA Competition Rules, Principles of USPSA Competition.)

Read the scoring with that sentence in mind and the formula stops looking arbitrary. Hit factor is points divided by time — diligentia over celeritas, in one number. Power factor decides whether you score major or minor, which sets what your C’s and D’s are worth — that is vis, priced into every hit that isn’t an A. DVC isn’t a motto that describes the scoring. The scoring is the motto, implemented.

That is why you can’t game one element without paying for it in another. Point-shoot fast and the points collapse; over-aim and the time does; score minor and the same C’s cost you more. Every stage is asking you the same three-part question, and your hit factor is your answer.

The question hit factor teaches you to ask

Run the example two more ways. Shoot it perfectly clean — all 18 A's, 90 points — in the same 14.50 and the hit factor is 6.2069. Keep the 82 points but shave a second and a half, and 82 ÷ 13.00 = 6.3077. In that example, the speed gain beats the accuracy gain — and on a different stage, with different hits, it flips. That's the analysis the sport actually rewards: after each stage, was the limiter time, or was it points? Chasing the wrong one is how shooters plateau.

After each of your matches, this card answers the question above — stage by stage, was it time or was it points?

Where hit factor shows up

• Stage results: the highest hit factor wins 100% of the stage's match points; everyone else earns their percentage of it. (Full walkthrough: how to read your PractiScore results.)
• Classifiers: your hit factor on a classifier stage, divided by its published High Hit Factor, is your classifier percentage — the number that builds your classification.

Run your own numbers

Enter any stage's hits, penalties, and time in the free hit factor calculator and try the what-ifs: what happens to the score if the D becomes an A? If the run is a second faster? That habit — reading your own stages instead of just your finish — is exactly what FirearmLog keeps for you match after match, so the answer stops being a guess.
