frenzy, "ridiculously early" or not, if that's what he's told, that's what USMA is told. Perhaps it is because he submitted them first to USMA? I am not an admissions counselor, so I can't say. But, I do know that ALL deadlines are shortened this year and a prospective cadet or mid would do well to keep a calendar close to hand.
If I were him I would contact my admissions counselor and/or ALO about the situation. They may have made an error in the letter or they may be able to push the deadline back.
USMAHopeful97, on my portal under "Your application is:" it says "
In order to be considered for an appointment, you must complete the following forms and/or take the approriate actions by November 10, 2015." Under that it says "USAF Academy Candidate Fitness Assessment". Does your portal have a different date? Is "USAF Academy Candidate Fitness Assessment" not listed where it's listed on mine?
