This was not an medschool interview, it was an interview that would help the committe write a composite letter that is going to go out to all the schools I applied to. In any case, it was one of those situations you could not argue with them too much because you have to find that balance of being honest and direct and at the same time, not too aggressive and confrontational/defensive. I just politely stated my side, as you have already suggested, but I did not push it, for fear of irritating them and risking a crappy recommendation. Oh well, I've been assured by the chair that the letter will be fine...they wanted to see if I could perform under pressure...nonetheless...
