Think long term- the only thing worse than a bad CFA keeping you out is to get in with a low CFA, then struggle to stay there.
Not talking about basketball throw here, or doing just OK on one item. But if you are below published average, much less near minimums on things like running, pushups, situps, and even pullups.... you are in for a struggle and will want to improve while you can.
We know cadets separated last year due to APFT issues. And more who are at risk, not in good standing due to APFT, mil movement, etc. Others with low military grades starting at CBT, and continuing on because they could not handle the physical stuff. Good kids, but in retrospect, totally ill-prepared for the physical side of USMA. Few are overweight, it's just a core conditioning thing.
DS is not a super athlete, but has kept at his training since even a applicant, and has been able to come within a few points of supermaxing the APFT each time. And it's more than just the APFT, it's upper body strength, and general stamina. Which means he was not the one who stopped the platoon on FTX because they were spent. Or had to repeat obstacle courses because of fitness issues. Or worse, wash out in your MIAD.
You don't want to be "that" cadet. You *do* want to be able to be the solid one brings the company performance up with APFT scores, Recondo, etc. And some of the PMA (Positive Mental Attitude) that comes with being able to hang in there in tough physical situations.
Your physical scores directly impact class rank as well, and performance often trickles into your military grade. Two big chunks of class rank, which impacts many aspects of cadet life... MIAD selection, leadership positions, and ultimately branching priority.
So don't think of the CFA as a way to get in.... work it as a long term goal. This does not mean you have to be a super athlete, just recognize it's part of being successful at USMA and prepare for it. This is an area completely within your control and you have the time to prepare.
