Rick, I'm a little confused but we're getting closer. How about we agree on a difficulty factor of 15 at any "range", but the difficulty factor must remain constant, range is the ONLY variable.
Now, I haven't shot an FT match yet but, I beleive it's only 1 shot per target. So lets say we print X number of sheets(whatever we agree on) and shoot just one shot per bull. People can see how close a person comes to scoring dead center. I'm cool with the +/- 10 per shot scoring but I think everybody will keep a tally of how many shots were outside the kill zone. Don't forget, we have to agree to "inside the circle" otherwise, on a real FT target it's a "split" which won't knok it down.
