Here is a data point: at PPW it was noted that only 54% of Plebes passed the initial PRT evaluation that is administered the first weekend of Plebe Summer (98% passed the actual PRT at the end of Plebe Summer). DS was very surprised at how many really out of shape young people reported for Plebe Summer, given the perceived emphasis on the CFA. Being in great shape makes PS much more tolerable. But I question if much weight is placed on the CFA (compared to other factors) in the admissions process. This does, however suggest that PS will whip the less-than-fit into shape.
