Thank you for your help on this. Much appreciated. I really do enjoy this game. We’re all in direct competition with ourselves so keeping track of scoring/progress/improvement is important. Want it right.
I really can't say what happened with the bug but reading the linked thread I can't see wgt changing anything now. Firstly it'd be a lot of work and also some would be really upset at being demoted.
So forgetting how you got here I checked your recent average changes and scores to get an idea of where you are now and this is what I noted.
I started after your 69 at KI when your aveage was 69.16. If we assume there were 19 rounds included in that average then there were 1314.04 strokes.
You then took 214 strokes for three rounds (80,68 +66) and your average was 69.45.
That would be (1314.04 + 214) 1,528.04 / 22 = 69.456
Finally after a 72 your current average is 69.57.
1,528.04 + 72 = 1,600.04 / 23 = 69.567.
Although this is slightly out at 69.456 that's probably as your average is only given to two decimal places, I reckon you have played 23 ranked rounds at your current tier (as of the 36/72 at St A's on the 4th).
Just as an example if the 69.16 included 10 rounds that's 691.6 strokes add the 214 = 905.6 / 13 = 69.66 . Which is a fairly long way out from the 69.45 it actually was (30 rounds would give an average a fair bit too low).
Looking at your score history I don't really see where that many rounds come from but that's how it seems to work out, unless I've done something wrong :-/
