The way the Army does it (not sure on how the academy does it if they do) is they take your height, weight, then they measure your neck and belly from the belly button. You can be up to 24% to get into the Army on the enlisted side. Once you're actually in the Army, that goes down to 21 percent I believe. With that being said I was 201 at 5'7", 38" belly and a 17.5" neck and I was right at 21% when I went through MEPS. At my last PT test I measured at 36" belly with a 16.5" neck at 184 pounds. Measure in at 18%.
Do not be discouraged if you have to get taped every time you take a PT test. The Army wants everyone to look like a stick based on their weight standards. It's a broken system that needs to change in my opinion. But anyways, use my measurements as a guide for where you're at now. My guess is they won't kick you out on R-day for being over tape. That would be silly. If you can't maintain the standard after beast, then I could see it being an issue.
Work hard to stay in shape and it'll be the least of your worries.
