Disclaimer - this question is not based on a real-life situation. Just curious, if self-rated players can be DQ'd up when their results are too good, is it also possible for somebody to be DQ'd down if their results are too bad? E.g. somebody self rates at 4.0, then plays a few matches and loses all of them with scores like 6:0, 6:1 to below-average 4.0 players - doesn't this warrant a DQ to 3.5 level the same way as beating the competition with the same scores would result in a DQ to 4.5? If yes, has anybody known/heard of this actually happening?
