CRobinson2038: The 9 under I rteferred to was best of the par fives in competition.I dntidn't realize it didn't
Nope, the best of 3's and 5's do not count towards your averages, but do count towards your overall stats.
Also try not to look at the scores by how many under you are, but the raw score. A 4 under at St A's F9 is a 32 (64 for average) yet the same 4 under at Oly F9 is a 30 (average 60).The St A's score may not move your average, the 30 will.
Basically you play x amount of games in a tier (TM I think is 40 games) before you become "saturated". At this point a better score is replaces your previous worst score - and this is why when you reach this point, initially your average will drop quickly, then it gets to the point where replacing "bad" scores becomes harder. Just keep plugging away. In your case I think your average may be as low as it is due to match play wins against legends, as I did not see many scores below 64, so potentially any score around this may knock out a higher score resulting in a drop.
Like I said it will happen but you add some 30's into the mix, you will tier up quickly. Just continue to play and enjoy the game, and before you know it, you will be saying "wtf, why am I teeing up in the car park and my master mates are playing from ladies tees" :)
