True, some people are very strong or very flexible but really bad at climbing and have a hard time climbing things quckly since they have to learn how to climb on the actual climbs they are trying to siege. Maybe this is true for entire sub-populations of climbing (it used to be too true in northern scandinavia when the climbing season was short and there were no good gyms), but for the elite, those who climb near full time, I would expect them to be very good at doing things that suit them fast.
