I don't think it's fair to say that climbing is linear or logarithmic. Since grades are both relative and consensus. Perhaps grades seem logarithmic when thinking of climbs near or at your limit and seem linear when thinking of climbs well below or well beyond it.
Perhaps the true grade of a climb is unknowable..
