I'm not really sure if you took in what YJ was telling you.
firemangeorge: My last below average score I shot was a 30. Dropped it something like .24 on my average to a 61.78.
(I'm not certain of this but I think it's 50 ranked rounds until saturation for TM-Legend.)
So your average was 62.02 and assume you were saturated with this round or before it.
That incldes 3,101 shots (50 x 62.02 = 3,101)
Your saturated average replaces your worst score included in the 50 rounds with the 30, which for averages is a 60.
If the worst score was a 36 (72) this would remove 12 shots from your total 3,101-12 = 3,089. to get your new average divide by 50 3,089/50=61.78.
As all your scores are included until saturation there will be some larger ones there to be replaced, so averages will often drop steeply immediately after it kicks in.
The bit I don't understand is "It had been at that average of 61.78 until today's 61.1 showed up"
I think the 30 you talk of was on Jan 3rd at PB since when you've had a 31 and quite a few 32's and 33's all or most of which I would expect to lower your average if, as I'm assuming, you became saturated around the start of the year. I think your average is right and if it was stuck at 61.78 that was the problem and it's now fixed.
