^ really the only way to avoid getting dq'd, if self rested, esp. once you reach a district or certainly section level event and "kick ***", is to have manipulated your dynamic rating such that out of level results don't result in three strikes. Anyone willing to go to such lengths will likely get a way with it unless an administrator is willing to step in and evaluate the situation for the benefit of the recreational game. The problem, in my opinion as a Captain of competitive teams that play straight up (including winning district at mixed this past year), is that these teams that may be cheating also lose at sectionals.
