For people who have a slow simspeed it should be relative to the other people in the game
Example - If one person is -2 less than the others over a period of more than 60 seconds
So sentons game is -3 but would be -1 without that person
This would be a useful mechanic as people with old laptop CPUS often do well slightly badly on the cpu test but after half an hour in game its just a waste of time. If they dont leave the game is lost through others leaving
internet lag/stutter is normally something that gets caught early on in my experience and is much less of an issue - the game is rehosted and problem goes away with a different player.
