Course rating question/ ideas

The TROYER rating of an FT course in sanctioned AAFTA competition is absolutely utilized. The GP ( Gran Prix ) scores across this country are based of minimal requirements to qualify.



LOL ... The Troyer difficulty rating system came to be exactly for the reason of measuring each target !!! The conditions of which shot etc .... DOH !!!



Wish to measure a shooters overall skill .... Watch there PERCENTILE average based on the shots that make up a match and weigh against match to match average of achievement / matches shot in the past.

You are giving me a headache. Seriously though, we do figure out the troyer rating for every target and which lanes are difficult and easy. The Troyer system is only a guide. Before that I just figured average target distance, again as a relative guide only. There are too many variables to drive you nuts if you want an absolute comparison.

If you want to see a sample of our spread sheet for a match at our club shoot me an email and I will send you one.

I try to have no duplicated yardages and also look at the options for ending with the most interesting and varied course possible at whatever venue I'm working on. I also HATE cold lines, so try to ensure the solidity of the mounting and leveling and look at string snags, visibility, etc. My mission is always for people to be challenged but not overwhelmed and have FUN.

JMO, but we put enough on our Match Directors as it is. 


Form where i sit, the Troyer rating system is best used as a planning tool for the match director.


I'll strongly second what Rich said. There's no way it can realistically be used to compare lanes or courses.

My friend, the Troyer system is used for every shot for every match… And especially for the Grand Prix‘s. Everything is so meticulously calculated… Including percentile of shots over 40 yards etc., distribution of shots… I digress.
when breaking down the difficulty of each shot, for each class, some factors come in to play. For example in a hunter class, having a 16 power scope measuring 50 to 55 yards is extremely difficult. Whereas in WFTF class all the effects of the winds are nearly doubled on your trajectory making things nearly twice is difficult to hit at distance. And then calculating this factor with the challenges of spring piston will throw your brain into a tailspin. I have thought about what you said in the past, and one of the only ways to really calculate this would be to go through every shot individually for every match… And that becomes a statistical nightmare for the directors. This is actually where I could see using some electrical match management software… i.e. Scantron or electrical targeting system would be able to do this type of calculation without thought. But that’s a whole different topic.

As you become more experienced, you will understand that all these factors come in to play when determining difficulty of a course, challenges of a class, and skill level of a shooter. For example a WFTF spring piston shooter shooting a 40 out of 52, is by far a much better shooter than an unlimited class shooter shooting 51 out of 52.
