ipsc/idpa scoring advice

[gaddygat]

Ran a few stages up on a private lane at burro last week, and scored matches on scoresheets almost identical to the ones used at Prado classifiers. Now I'm looking for a resource to show me his to score entrants, or a website that I can plug in info and have scored; any recommendations? Some stages had 2-3 strings, so do I average out times of the strings or add times together ? Still really new to this but trying to make the most of the private lane time I can, when I can get it. Thanks for any recommendations

This is for USPSA:

IDPA is time plus 1/2 points down. So if you shoot a stage in 11.5 seconds, and are 7 points down, you add 3.5 to 11.5 for a 15 total.

For USPSA, it's earned points, minus mikes and procedurals, divided by time. Called a hit factor. Shooter with the highest hit factor takes all the stage points, and everyone else gets a percentage of that based on their hit factor.

from AR15.com

USPSA scoring

Your time was 20.32s
your hit factor is the # of points divided by your time

you shot a hf of 2.5591 because you shot 52pts in 20.32s.


you are ranked by hit factor and given stage points depending on your hit factor as a percentage of the winners hit factor

The winner had a hit factor of 3.6

the stage winner gets all the stage points (70 pts), even if you shot all "A"s he gets all the points. you get a percentage of the stage points based on your hit factor compare to the winner

So
your hit factor was 71% of the winners hit factor, so you only get 71% of the stage points


Its a little confusing when you first start. but I like the scoring system, because depending on the hit factor, more or less weight is given to accuracy or speed. knowing what you are going to shoot a stage in, you can detrmine if you to push speed or if all "A"s are need


To expand further
you shot 52pts of the 70 available, about 75% of the points for the stage... you should be around 90%. you would have to had shot the stage 6s faster to get the same hit factor as the winner with your same points, but only 1 sec faster if you shot all "A"s

on a low hit factor stage, shooting all "A" is a must, with a 2.5 hit factor, you are getting 2.5 points for every sec, for you have 2 sec to shoot an A. or .4 sec for each point. if you knew you have .4s to shoot an A instead of a C, you would take the extra time, 1.2 sec to shoot a A instead of a D.

now on a high hit factor say 12. you are getting 12 points per sec or .08sec per point, now its not worth making a C hit up with an A and but it would make sense to make up a D.

ipsc/uspsa and idpa are scored entirely differently. what exactly are you trying to do?

[speedrrracer]

Leethe4th has started the USPSA complexity, but it goes another level further (match points), which is why it's best to answer rmatt's question: what, exactly, are you trying to accomplish?

A stage you created off on your own has no meaning nationally, unless you are a sanctioned match in your discipline. If you are, then you'll want to input your scores into practiscore with your club's ID, or however your sanctioning body wants to receive the results.

If not, well, that's part of the reason why IDPA and USPSA have classifiers, so you can compare yourself nationally. IDPA posts their classifier rankings, and advan031 posted the best way to find out your national rank for a given USPSA classifier.

I've attended one classifier at Prado this last January, so I recreated those classifier stages, along with creating similar scoresheets. I want to be able to practice on my own (without having to go to a match) to see how I've progressed. To judge that progression, I want to start with a baseline of stage times/points, and reshoot those after a few months of practicing to see where I've improved, and where my deficiencies may lie. I haven't created any stages on my own, but I have been using classifier stage designs from ipsc

[rmatt]

idpa classifier or uspsa classifier?

but yeah, if you are replicating uspsa classifiers then just figure your hitfactor and dump it into classifier calc to see where you stand.

You are better off to shoot the IDPA classifier to know where you are at right away. It is a 90 round course scored as time plus points. The divisions and classes are shown on the scoresheet. You would need several USPSA classifiers to know where you stand, assuming the classifier app has the particular number you ran, because there are thousands of them.

Gaddygat,

Just shot you an email, perhaps it would help you.
