YankeeJim:what format were you playing?
Think this is the main question since even the par 3 course will count in stats.
Alt-shot, matchplay, skins, Ctth/blitz won't count, nor will practice rounds. Also, if it was a ranked round, if you don't finish the round it will not count either.
*edit...
Judging by the op's recent activity and wall posts, I'm willing to bet this HIO was during an alt-shot game at Oakmont.
