YankeeJim:
genorb: for sure something has changed. Indeed, my average was 54.03 before the change and I posted a 58 and it went up to 54.04.
This makes sense. Just like Legend averages change until you get that 400th round. In your case your average should have gone up for anything over 54.
Well Jim that's not so obvious. The way they calculate average now is even more strange than before. Indeed, this is not the average over all the round I have played as legend for sure (my average would be larger). This is not either the average of my 500 best round (otherwise this 58 wouldn't have changed anything).
My guess is that they take the best 400 rounds before the change and to this, they will add the next 100 rounds. Indeed, before the change my average was 54.03 over my best 400 rounds. This means 400*54.03 = 21612. Now I have posted one 58 after the change, so we have 21612 + 58 = 21670 for 401 games. This leads to the average 21670 / 401 = 54.04 (with round off).
I will confirm this when I will have played more rounds to see of this procedure is correct.
My guess also is that for those who will turn legend after the change, the average will be computed over their 500 best round (meaning also that you will need to play 500 rounds before your average doesn't go up). But this can only be confirm by a new legend who will take note of all his rounds.
