In a totally clean, competitive TdF you would expect the gaps to be small nowadays as all the riders prepare in very similar ways and no-one would have any big advantage in the way they prepare and are looked after than the others. If all the top GC guys in the EPO era were on the gear then again u would expect fairly small gaps but the doping factor and the complexities of exactly who was doing what and how effective it was as a performance booster would probably affect the size of time gaps.
I think generally over recent decades you see the time gaps becoming closer as the sport becomes increasingly sports science based and 'homogenous', i.e. all the riders train in similar ways. Going back a few decades yr bound to see bigger gaps coz the sport as a whole was less of a level playing field and not so 'professional'
I guess thats a round about way of saying Nibali's performance seems pretty dubious to me. For one guy to totally dominate a bunch of others who every stage ride to a very similar level is a bit suspicious. Could a clean Nibali really dominate a guy like Valverde so much, day after day? I mean Valverde is maybe not the very best but he's proven since returning from the ban to be very close to the best climbers consistently and Nibali has just toyed with him
