@Satoshi Kyou Let's just take it easy, there is no reason to start an argument over something so small and trivial. You can still one have Hayate recover from being tripped by one somersault or another move. Two Shinrei might do something out of the ordinary and prevent her from falling.
Shinrei actually wanted to knock Hayato out after for that one remark he made toward him. However, he is far experienced and knows better than that. He can't just openly ignore the rules unless it's something he absolutely wants nothing to do with. I see him getting in trouble at least for not showing up for Turbo Dueling class because he sees as a pointless suicidal tendency class where people play bumper cars and wreck each other.
