Steve,
I really appreciate what you are trying to do for flight archery. I see you trying to keep it as relevant as possible for the average hunter or target shooter as possible. But it is kind of like riding lawnmower racing. It starts with a few old guys in the neighborhood racing their clunkers in a nearby vacant lot, and before long, they start tweaking the machines to the point that they are worthless for mowing a lawn, but can zip around a track at 100mph!
I keep trying to think of an easy way to set up a flight shoot with normal working-type bows and I really struggle with it. 40-50+ years ago, the flight round had to be shot with the same bows and arrows that were used for earlier target rounds. Even then, some folks, like Harry Drake or the Pierson's, may have been willing to lose at the target rounds but make up for it on the flight round.
The easiest flight format I've seen is to let people shoot what they want and lump the results all together. What makes it interesting is the added info that describe the draw weight, bow type, arrow, string, and shooting style. I think this format can really shine a light on someone who may not come in first, but happened to shoot a primitive bow, natural string and primitive arrows nearly as far as the modern bows. The Polish shoot results are really interesting to read because of the variety of bows that were shot together. It didn't seem to hurt the competition given the large number of shooters who participate.
