"Old Men Can't Jump"
I think the whole premise of this discussion should be rephrased to "Old Men Can't Jump". Most everything you are spewing out Bruce is complete and bloody rubbish. I disagree with all of your proposals and reasons behind them. 95% of all stats are made up. 1/3 of jump putts are illegal? Yeah, ok, NOT. If it is very clear without question that someone has no supporting point on the playing surface upon release of the disc, then make the call. But if the release of disc and supporting point non contact are almost simultaneously, then seriously are you going to make that big of a deal about it? You come up with these off-the-wall ideas that are a) more intrusive for a TD (marking fairways out to 30m vs. a 10m circle), b) goes against the speed of play rule (dude, I'm going to go walk off 30m now vs. 10m), and c) makes the sport look pathetic (carry a little hanky and place behind your disc, or draw out a string).
A jump putt takes skill just like a perfectly executed roller or a 350ft accurate thumber. If a player exhibits a well executed jump putt then congrats to them. In my experience and the players I have competed with, jump putts are the least significant matter that needs to be addressed in this sport. Are there players that violate stance violations with their particular attempt at jump putting, yes? The same can be said about players that miss their LOP on fairway approaches. Typically competitive players will respectfully pull these players aside, and quietly address the issue with courtesy and respect to let the player know of these small insignificant nuances. Rarely is it the case that a player is attempting to gain an advantage from these minor miscues. But when it becomes apparent or repetitive then they should be openly addressed.
I think our attention of the embodiment of our sport needs to be steered in a different direction, how to grow the sport, how to increase viewership, how to encourage ethical sportsmanship of a gentleman's game.
Just to give you one example where I see the PDGA moving away from this ideology. We say this is a self-officiating sport, yet per a 2013 rule change, now a player cannot call a stance violation on themselves.
