I try to let students alone during competition, especially if I'm in the same competition myself.
But this has become an issue in our Junior tournaments in the area. Some people expect the coaching, that's why the coaches are there and some are adamant against it. We don't have anything in our tournament rules about coaching , or being coached, while bowling but we've gotten a lot of complaints about it. Honestly I think that if the coaches are allowed to be there, then they should be allowed to coach/help their students. But it always dribbles down to which program has the best coaches and then the other programs complain when the kids are coached by the better programs. However, I think once you get into the adult ranks that professional coaching during competition in tournaments should not be allowed.
During team competition I think that its imperative that a team help each other out. So I don't consider that "coaching" in the context we are using in this thread. Teammates should help each other, that's why its a team.
