I don't believe that is correct . These are very accurate numbers . There are situations that allow earlier tiering up . but are rare and require excessive playing .
It is more likely that your first round after you tiered up was a 69 . making that your new average .
It is/was correct as I stated. My average was 69.2 after what turned out to be my last round as Tour Pro. I suppose this was one of those rare situations.
Actually, my average after my first round as Master was 76 as I played with the newer/different balls, and from longer tees ( a 9-hole 38).
BTW - I brought this up in an older, very related, thread from a search to keep this information together instead of scattered throughout even more threads.
