Joakimbl & wfsaplau: Seems to me to be a pretty defeatist attitude to say "the players are a bunch of uninterested wimps who'll never call anything, so why change". I don't want to spend too much time addressing if things should change as not changing anything is a very easy option and I'd rather talk about what/how we should change. That said I'll cover a few of the points raised.
Other sports have bad calls: All sports I can think of have tweaked rules to minimise/discourage infractions or introduced technology to identify them where they are borderline. Also those calls are by independent parties that the players have to suck it up from.
Jump/walk putts aren't an issue: The committee reviewed available video and concluded that up to 1/3 were illegal. Seems a big enough issue to me and missing the mark is just as much a problem.
There is no competitive advantage gained when most of these rules or ignored, bent or not called: Then why have the rule? Either have a rule that matters and is enforceable, or write a new one. That's exactly what we're discussing. I think it matters, and is unenforceable. The latter is backed up by the fact that it isn't enforced.
No rule should be written or re-written to make it more "easily enforceable": Turn that one around. How about I introduce a rule in American Football that the QB must be touching the laces on the ball at the point of release. It's unenforceable and doesn't influence the outcome of the throw, so it's a bad rule. (I'm a Brit, forgive me if my analogy is somehow weak).
A jump putt is a skill: No, a legal jump putt is a skill, but it's not possible to tell in real time. I'd welcome any suggestion of how it might be possible to keep them whilst making it possible to easily call violations.
Ok, back to the actual discussion...
Captain: Yes, you would be moving it out. The only way to prevent players from trying a jump/walk throw is to deny them a follow through. Doing that everywhere seems too big a change, so it's a case of finding a distance that discourages it whilst remaining fair to shorter throwers. Or finding a way to keep it but make it easy to see if it's illegal.
Bruce_brakel: Interesting thought, essentially a group decision where "I don't know" means "I abstain". I think part of the problem is that most successful calls I see are seconded by the thrower themselves. While it's currently easy to see someone missing their mark it's difficult for the thrower to confirm.
Krupika/chuck: I don't agree that seeing if someone is on an infinitely thin LOP line is easy, I think most players would be very satisfied with 'behind the mini'. The typical disc is 21-22cm wide, so to be certain of hitting a 30x30 lie you'd need to be 'behind the disc', or very fractionally (<2") to the side. I agree that the percentage of miscalled or uncalled edge cases would not change, but I think you'd see a dramatic reduction in the number of those cases.
