Once saturation is reached although the scores wont raise the avg , it will still record and become a score to be played down .
Recorded, yes, but counting in, no.
Once the pool of 200 Champion scores is filled for you, higher scores will be "out" forever. Only the scores in the pool have to be replaced one by one to move the average down (not that it matters much with no tier to promote to).
Now before saturation playing up the avg will only prolong tier elevation for a short while .
Only for the duration of that game, I'm sure. As I said before, all those precious high scores have no effect eventually. Take the 70, 67, 65, 62 scores in my example - in the end, it's irrelevant if they were posted or not.
But it too will cause the game to play easier .
I understand your point now and can neither confirm nor object.
