Just tell him you had it under control. As far as tolerance level, mines pretty high, however if I'm working with a partner or partners who don't have a high one (although I'd be willing to be they've got a fairly high one, especially at the V level)--then I'm backing them up no matter how little the coach said or whatever that he got a T from my partner.
By the way...I'm getting ready to go do a 5/6th grade game to fill my time on Wednesdays!
These are always interesting.
