My point is that even if no one has ever scored one lower than par, that's not a sufficient reason to raise par. Why not? Just because they haven't doesn't mean they won't / it's possible.
[bold above is my quick response]
An example is Beaver State Fling Presented by KEEN - National Tour 2017/Milo McIver East/ Hole 17. In 83 rounds of play by 1000ish-rated players, no 2s were recorded, but 82% of those players got a 3. That hole is par 3. It does not need to have any 2s at all to prove it is a par 3.
Is it birdieable? Maybe, maybe not. Doesn't matter.
I think it does matter!
A few prefaces:
A lot of people TRY to make disc golf (dg) "different" than golf (bg) but precedence has been set - dg IS "golf".
As some others, I happen to be in the camp of par is NOT an "average" (of even the greatest players), therefore you can trick up a hole all you want and par, birdie, bogie, etc. will NOT change.
In bg, on a 3par, one can get an eagle (ace), birdie, par, bogie, etc., but albatrosses aren't (as zeros and minus numbers aren't). Any 'drive able 4par' is REALLY just a 3par usually fraught with danger that the tournament has set up as a 4par "for viewer's like", drama, and the like. Personally I don't like that they do such but that's just me. ALL 3pars can be aced...and, yes, some of these sham 4pars (that aren't REALLY 4's) can be also.
So working on the premise that all 3pars CAN be aced (remember we ARE golf!)...
...your brain can probably travel to all sorts of scenarios - and a lot faster than I can type on a silly phone with a stylus!
Therefore:
If a hole can't be aced, it's a 4par (or higher...determined by if it can't be "had" in 2, it's a 5par, etc.)
If a hole can be aced, it's a 3par.
If a hole isn't giving you the "scoring spread" or "challenge" or "...whatever..." you're looking for, PAR is not the problem. Design is! And thus I bow to Steve's post numerous posts prior (the one where he said something about it being a design issue).
But as I've said numerous times before: if JB, JH, myself, LL, and (name any other reputable designer) looked at 100 holes in person, the number of holes that we wouldn't agree on its par would probably be on 1 (maybe 2) fingers. Par is like that senator asked if he knew the definition of porn - and said he knew it if he saw it. Thus is par.
Have at it
