“Dirty” Hit Factor math is actually extremely helpful for me.
In minor HF USPSA scoring, an A nets you 5 points, a C 3 points and a D 1 point.
Add up all the points available. This is the most you can score. After my run, I can subtract 2 points for each C, and 4 for each D. Or, thinking another way, a D “costs” the same as 2 C’s.
Do a run to get a time baseline. Divide the time by the max points to get the max Hot Factor for that time.
I like to use some ‘typical’ hit factors for my dirty math.
On a fast HF stage, like El Prez, 60 points in 6 secs will get a 60 pts / 6s = 10 Hit Factor, or 10 points/sec. Or, each point is worth a 10th of a second. A Charlie costs 2 points, or is the same as ading 2/10ths of a second to your time. A D costs 4 points, or 4/10’s of a second.
On a more typical 32 round field course at our matches, one could earn 32*5 = 160 points. If you run it clean in about 27 seconds, you would net a 6 HF. At 6HF, or 6 Points per second, a C costs 2 points, or 1/3 of a second. A D costs 4 points, or 2/3 of a second. A miss that isn’t mde up costs 5 points, plus a 10 point penalty, or 2.5 seconds!
You can do a lot of aiming in 2.5 seconds, and spending an extra 1-2 tenths of a second cleaning up a sight picture from a D to a C to an A actually pays off.
Maybe this helps, maybe it makes it clear as mud.

I do quick HF calculations, but use time instead of points, which I learned from TGO. I mostly use either a 5 or 10 HF, and minor scoring,
On a 5 HF stage, a C costs .40, a D .80, and a miss 3.0 seconds. On a 10 HF stage, half those amounts.

I can see the ease of scoring on a USPSA target in accordance with which zone you hit. Is there a standard that works best? A zone = 5 points? 10?
How/Who determines PAR? Do you adjust anything for distance?
I know these are basic questions- but I’ve never worked with H/F before!

Here is a hit factor shooter. One of the most stupifying shooting vids I have ever seen! One charlie shot on this stage.
I couldn't find it on youtube but I suspect Ben's page is wide open.

Yes! That is what we call the "wheelhouse".

Sorta, but not really. If you're doing a FAST drill or something else, Hit Factor is kinda "why bother": You either got your hits and made the time cut off or you suck.
Hit Factor scoring really shines on intermediate drills where you have to shoot, go somewhere/perform some task, then shoot again.
I'd even venture to say that, while we calculate hit factor for classifiers, we just need the times and "shape of the hits" in practice to determine if they're useful or not. Most classifiers are just too condensed for hit factor to really become of value...
The subtle distinction here is the "in practice" bit...
The question is HOW fast is useful? This is where going backwards from a classifier to determine the speed at the different classifications becomes useful - but that isn't practice or using HF scoring in practice. It is more like using the HF to determine the yardstick and goal.to improve the speed until under standard
Sorry - gotta go get some pants on...
That's interesting. Like Dr. No's point here in the past about "80% moving".
Because if its only shooting weird things can happen.
Two shooters. Task for easy math is D2 at 15 yards
#1 shoots an A and a D in 1.50 seconds. HF 4.0
#2 shoots two Cs in 2.0 seconds. HF 3.0
The D is wide "miss" by #1
The two Cs might be near misses at 12:00 of the A zone by #2.
By HF #1 is the better shooter.
But then as you said, add 20 more targets with movement across 20 or 30 yards of running and shooting in and shooting out of positions and the HF considering all that time of movement comes into play heavily to sort things out.

Nothing requires you to use USPSA minor scoring and USPSA targets. Design your own target zones and assign points on whatever basis you feel relevant to your shooting.
Don’t get sidetracked by the movement discussion. First, classifiers where most people get their classification rarely involve movement. Second, to quote JJ, it is the 10 percent of movement into and out of position, where the time is made or lost. For the length of most USPSA stages, flat running is hardly a factor as distances are short, and often it involves shooting on the move.

This.
Part of the problem is that people define "drill" in a variety of ways. If we're just talking about short shooting drills (~5-10 shots), then HF scoring get more and more limited.
Treat those drills more like pass-fail, timed. You may try to decrease the time aspect, tho, to make it more challenging...
...and this is where USPSA gets interesting: Shooting the gun is one task, but movement, efficiency, etc are all other things that add up. Tracking efficiency of movement, etc using HFactor scoring can help someone figure out where they're lacking.But then as you said, add 20 more targets with movement across 20 or 30 yards of running and shooting in and shooting out of positions and the HF considering all that time of movement comes into play heavily to sort things out.
