To all of the above, here is THE definition of par: Read it carefully and apply it everywhere, and we are done. No more need for discussion.

800.02 Definitions
Par
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, allowing two throws from close range to hole out.
Take the definition of expert to mean 1000-rated player. (Now that we have ratings, we can use this more precise clarification of what is meant by "expert").
Recognize that the intent of "two close range throws" means the throw where you try to park it and the throw where you try to put it in the basket. (If it meant two putts, it would have said two putts.)
With those clarifications...
Disc golf par is not the average score a scratch player will make – it is lower than that.
It is
errorless play by an expert. Shooting par would result in a round rating of about 1020 or so. That's between cashing and winning an Open field.
So, it
is somehow relative to what top pros are likely to shoot. It is NOT inherently easy to shoot under that. No one would be shooting 70 under for a tournament or 18 under for a round.
Obviously, this is the par that should be used for tournament play, but it should also be the par that is used everywhere else.
It is already is universally agreed on (it's the only one in the rules). It is not universally
applied, but that is the fault of people who set par in tournaments or make tee signs.
I'd make one extension: The "expert" player could be at another skill level if it is appropriate for the course or the tournament being played. However, if anything other than a 1000-rated player is the "expert", then there should be a modifier attached. For example, Blue Par would mean the score a 950-rated player would be expected to make on a given hole with errorless play, etc.
