The purpose of that table was never to predict or correlate racing category. It is meant to be a tool to look at an individual's areas of strength and weakness to make appropriate training adjustments. Andy was disturbed that so many people were misusing it that for a while he removed the category designators, but people kept the older versions in circulation so they were put back. A full explanation of power profiling is here, https://www.cyclingpeakssoftware.com/...11/profile.asp, and to extract two quotes,

"... such category-based values would seem to have limited practical use - after all, the best measure of a rider's competitive ability relative to that of others is their actual race performance, not their power output."

"... the primary comparison would therefore be the rider against themselves, and not (directly) against others. Such information could be then used to help plan an appropriate training program, evaluate the effectiveness thereof, and to possibly identify events where an individual might be expected to achieve the greatest success."
