I agree. There is a lot of theoretical watt and watt/kg estimates from climbs that have a lot of history, like Alpe d'Huez. One thing I try to keep in mind is, most of those climbs are much longer than the 16 to 17 minute final climb of stage 18. Alpe d'Huez, for example, is a 40 minute -plus climb for the top racers. Obviously, the duration of a climb greatly affects the average power possible.
