Well, I Think that a 77 in a 9 hole, after a quick look at your stats and your average performance in not right!
I did found (the hard way) that WGT deviation, "the beast" called by someones, exist and can mess with your game very bad. And what is funny is than in specific situation can be worst.
I played yesterdat my first 1000cr ready to go, on the new Course. Why? because I won credits in all the ready to go's I entered in that course (23+ so far) and I scored well in most of them.
and this were my scores: 63, 59, 63, 61, 63, 64, 60, 63, 60, 62, 65, 68, 65, 61, 65, 62, 64, 62, 62, 66, 60,......... with an average of 63.
But in the 1000cr ready to go, every time I managed to get to -2 nex hole was followed by a triple bogey. I finished with a triple bogey on 15, birdie 17 and eagle #18 for a beautiful 70. I had 3 triple bogeys in the round, and two of them by 4 putting the green. I missed from 2-3 feet in magical ways.
I play 100-200 cr ready to go all the time, with good and starndar deviations.
I have entered 3 high stakes ready to go so far, two 500cr and one of 1000cr... and all three of them I wasn't able to score under par. like game was set up for a SCORE CONTROL.
I was playing very well, proof is that I birdie and eagle most of the holes... to finish -2 but... it doesn't feel right when you know that deviation you are getting is not random at all.
anyway just sharing a bad experience here! Same way I had this bad deviation I had other good ones like my fist 55 in the winter tour qualification few days goo....
