Gator,
A low platelet count might cause them not to recommend a waiver. I'm not trying to be a wise ass, but from the Navy's and NAMI's perspective, recommending or not recommending a waiver for you, or anyone else for that matter, is a business decision, pure and simple. To my knowledge, you have no unique skill set that the Navy desperately needs, and we have not spent any significant amount of money on you as of now. Even giving you a waiver for commissioning hasn't cost us all that much, since the only money we'll spend is whatever OCS costs us in salary and training costs. Until you get commissioned, there is little financial down side to bringing you in. However, once you're commissioned, we become potentially responsible for your health care until you die. Add in the cost of getting a set of wings (figure at least a couple million bucks), and if some preexisting illness means we're not going to be able to amortize that cost over a career, the decision makers might rather spend that money on someone with no known medical skeletons in their closet.
I agree that you're probably going to do ok in life, and have no problems. You may perform brilliantly in the Navy and become the next CNO. The question today is whether or not someone in the Navy wants to gamble a few million bucks on you by recommending a waiver for flight training.
