He obviously would. However, assuming that an expert can make a "recovery" shot, at some likelihood reasonably close to his likelihood of making an errant shot, the median score should still be par. The only time this wouldn't be the case is if you were dealing with a hole with excessively abundant and punitive hazards.
Let's look at the toughest possible median-score par 3, where barely 50% of the players get 3 or better. That means half the players have an unrecovered error, right?
To me, that says 79.37% of the players avoid making an unrecoverable error on the first throw, and 79.37% of the players avoid making an unrecoverable error on the second throw, so only 63.00%% are still on track for par. Then, on the third throw, 79.37% of the players avoid an unrecoverable error, leaving 50.00% of players successfully getting par.
Now tack on one more throw to that par 3 by moving the tee back one throw. Make that throw just as hard as the other 3, so that 79.37% of players can do it successfully. This par 4 takes the same quality of play as the par 3, so it should be just as tough, or the toughest possible par 4. Since only 39.69% of the players successfully completed all four throws, that would be the equivalent cutoff point for par 4.
This is why it's important to look beyond the statistics and look at how a hole physically plays to make a par determination. I think in many cases the median could reasonably indicate a par that is less than "throws to reach plus two", but I would suggest that if it ever indicated a par greater than that, the true par should be "throws to reach plus two".
I agree human review of the physical hole is good, no matter the statistic. That's why I would not define par according to a statistic.
I'm having trouble picturing a hole where the median score would be higher than "throws to reach plus two". Wouldn't that indicate it actually takes another throw to "reach"?
