Playing this course might bias towards increasing a players average with lack of more birdie opportunities from par 3 and par 5 holes... I don't know. Or the opposite. But why deny others a chance at this great course and have it count for them?
"Best of hardest holes" might not be considered realistic either for a true calculation of a player's average if holes were chosen statistically difficult from lots of past performances. So from a pure golf point of view this would also bias a player's average and should be tossed?
Extreme golf purists would welcome your request and vote to throw out Best of hardest holes and also ask that only single play stroke rounds with uneven lies be counted towards a players average. Anything else is not really a true round of golf.
It just seems that this approach would remove more fun from the game rather than add to it.
