One thing to note about pros vs. joes on climbs is the shift in which energy system each person is using or able to use.
A joe may take over an hour on a climb. As part of a ride, they won't be able to throw ftp power at the climb.
A pro may only take 20min on the same climb. That's a lot different energy system than the joe likely going at "tempo" or "SS".
The energy systems get even more drastically different on shorter climbs like Cat 3's. A pro likely to go sub-10min on the climb, and a joe likely pushing 20min+ and grinding out at maybe ftp. But likely SS or tempo.
Just thinking aloud.......
