Yes. I don't think it makes much sense, in a "race to 1 million" event, to include players who have already achieved a million points. If I remember correctly, the "race to 500K" excluded anyone who had gotten a kill screen, which was logical.
It seems to me that the spirit of this should be, "who can get there first?"
Don't get me wrong, I want a Brian Allen Prize Pack as much as anybody, but how much chance do I have if, say, Ben and Ross are going for it?
