Just
* Stop the definition at "As determined by the Director, the score an expert disc golfer would be expected to make on a given hole with errorless play under ordinary weather conditions."
* Define an expert disc golfer as 1000-rate player
* Look to see (or estimate) which score at least 37% of 1000-rated players are getting.
That's par. All there is to talk about is whether 1000 or 37% are the right parameters.
Done. Fixes every problem. You're welcome.
I agree with your definition/s of par but not the
Blue words.
The problem is that when you (or I) would tell someone, "this course's Par is 47", they would say, "oh yeah - whose Par is that?" I would say "What do you mean - its par and par is par. Its just par". And so we would have "Just Par" as this new definition of Par.
And "Just Par" would co-exist with Course, Sign, Pro, Beginner, CR, SA and Rec Par. And nothing would change.
Or maybe the PDGA would change their official definition to what you suggest. And then Just Par would also go by the nickname PDGA Par.
Another issue with what you suggest is that there are plenty of people in influential positions (who make signs, design courses, run parks etc) who have no good grasp on what a 1000 rated player is.....much less how 37% of 1000 rated players will score on a hole or a course. But, everyone knows how to measure 300'.
Even if the decider is completely familiar with 1000 rated players, scoring averages, standard deviations, etc......what if the hole produces results that are 50% 4's and 50% 5's for 1000 rated players. Who is the arbiter to assign a Par value to that? If there is just one hole like this on a course, no big deal. But what if there are 6 or 7 such holes (including of course, 2.5 and 3.5 averages)?
To my thinking at least, your definition fixes only a small part of the problem.
