The gamesmanship at the end definitely skewed the time, so I'm not confident it can be compared to former editions.
I think there were some wasted seconds at the end, but hard to determine how much. The real time race log says they initially waited for Nibs following his crash, but apparently it was very brief, with Bardet not wanting to wait. Also, the time to go the next 500 m was about 1:30, in line with what they had been doing before (3 min per km, about what they averaged the whole way). So they couldn't have waited very long. At one point it says Nibs was 30 seconds down, then it says Nibs was 50 seconds down with 1 km to go. Surely there's no way he could have gained 30-35 seconds in the last km? Unless they were really dicking around?
In any case, I think a max of 30 seconds lost at the end, so maybe it could have been 40:45. The point about this being a different stage is valid, though Froome was much closer to his 2013 and 2015 times--maybe almost exactly the same if you allow 30 seconds wasted--than Quintana was.
