Anybody who asks Jake What's my percentage? or How do I calculate my percentage? while having contributed equations, postulations, or prose to one of the many ballistics and physics threads will face public humiliation.

Sorry if my post was a bit cryptic. ;)

I'm hoping to point out that...pretty much...all the info that anybody needs to figure out what their classifer will come in at...

...all that info is already in the threads.

You might have to do a little bit of "figuring"...but, the info is there.

Lets not take advantage of the good nature of some of the members. If you can do your own algebra/math...please do so.

If you need some help figuring out how to do the math...just ask.

(As Eric mentioned...we do seem to have quite a few members that know their way around an HP. I am sure they would be happy to help out.)

Here's how I've been doing it (which I only figured out today :)):

To determine HHF:

The HF for the shooter in your division that you found is to its corresponding percent as the HHF is to 100%.

But you don't even need to calc the HHF, actually, if you have a HF and a corresponding percent, you have all you need to figure your percentage:

Welcome back to high school math class:

Your HF is to its percent as the HF for the shooter you found is to its percent.

'X' is your unknown national percentage

'Known HF' is the HF for the shooter you found in your division that had a percentage attached to it

'Known Percent' is that shooters percent

<see attached image>

Resolve for X. Ta da.

Or you could just wait for USPSA to do it for you :)

known % / known HF = multiplier. ( or Sand/Grand bagger quotient <_< )

Multiplier can be used to figure HHF, HF for a given %age, and vice versa.

EX:

Shooter M shot 9.5 HF in L10 on CM99-1234. Shooter M's % was 85.2%

85.2/9.5=8.9684 8.9684 is the Sand/Grand bagger quotient

Your H/F was 6.3

6.3 x 8.9684 = 56.5%

To figure what a H/F for a %age is:

100% = 100/8.9684 = 11.15 so 11.15 < is HHF.

75% = 75/8.9684 = 8.3626

so an 8.3626 HF equals 75% the bottom of an A class score for 99-1234.

Keep in mind that each division has a different value.

One more thing. If you know the "Sand/Grandbagger quotient" then you can practice and "know what you need"

Using the CM 99-1234 example, let's say that it's a 60 pt Comstock stage and you know the the S/GQ is 8.9684.

100/8.9684 = 11.1502 which is the HHF

then divide the pts (60) by the HHF (11.1502)

100% = shoot clean in 5.38 sec

Yeah, but.. L10, Prod and Revo HHF's are merely calculated off the Lim HHF-- once you know that, you can figure out the rest.
