You get strikes by beating players at the top of the level by a sufficient score to push your dynamic rating well out of level. It is quite possible that your teammate got three strikes from beating benchmark players - I'm just saying that beating a benchmark doesn't guarantee you a strike. I would argue, though, that a self rated player winning matches at state championships probably self rated at too low a level. With that in mind, a DQ can be appropriate. I was on a team a few years ago with several self rated players. Two were DQ'd during the seasaon - and they should have been.
