HWei:In order to regain your completion dot indicator is by playing alternate games ,my guess 2 - 4 times will somewhat gradually bring your completion record back to green may take some time .
I'm afraid that this won't work because to my best knowledge, A/S games have been excluded from the completion count. The best cure is Blitz games AFAIK with a reliable friend (including reliable internet surrounding). You need not look for the results, just make sure that you finish the games until the game menu or a "repeat".
I agree about the patience warning because apparently there are 100 games in a FIFO stack (first in, first out) for this stats, and you have to push out a certain number of incompletes (along with the "good" counts in between) before the indicator improves. For a virgin green button, 100 rounds are necessary from the last disconnect.
