Thanks you all guys. Happy to help the community.

So for the next 500 rounds, a Legend players average will continue to increase if the player can not shoot a low sub-30 round?
Before the last update the legend average was computed using your best ever 400 ranked rounds (regular free tourneys, RG and CC tourneys). So if you hadn't play yet 400 rounds, your average was just your real average. Once you had played more than 400 rounds, the average was computed with your best 400 rounds.
Now they have changed this with the inroduction of this Tour Legend tier. The average is computed with your best ever 500 rounds.
However, they had a problem with players having played more than 400 rounds (or even more than 500 rounds). I guess you and I have played more than 500 rounds as legend (at least that's true for me, but I guess it's true for you too since you have 3500+ rounds in total).
So they could have used our 500 best rounds to compute a new average and if this new average was below 60 we would be moved to Tour Legend tier overnight. But I suspect that they were keeping only the best 400 scores for each legend player in their data base. So they were unable to compute a new average with our 500 best rounds because they do not know what are our 500 best scores. So we need to play at least 100 additional rounds to feed their data base in order to compute an average based on 500 rounds and no longer on 400 rounds. That's my guess why we need to play those 100 rounds.

Once a Legend player has passed the 500 ranked round threshold, will that players average start to decrease to the needed sub-60 level, thus becoming a Tour Legend player?
Once a legend have played 500 rounds, his average will no longer increase but only decrease, whatever the scores posted, like before the update where it was 400 rounds. Once 500 rounds have been played, as soon as your average is equal or below 60, you move to Tour Legend.
For those who have already played 400+ rounds before the update, their average will no longer increase once they will have played 100 additional rounds after the update. Once you have played those 100 additional rounds, as soon as your average is equal or below 60, you move to Tour Legend.
I hope I was clear enough.
