I have no objection to getting multiple 'excellents'.
By the way, if an additional rating (superb, bravissimo, wow!, whatever)
were added, do you think people would use it appropriately (that is,
rarely), or do you think it would soon degenerate to having the same
meaning that excellent does now?
I suppose there's a chess variant in that -- if you move your piece too
often, it degenerates to something weaker. This rule eliminates perpetual
check!
