Is this the video you meant to link? http://www.youtube.com/watch?v=z0FwoWEs_SY
If so, there is a mix on this video. I'd say a number of these rallies show higher than average net clearance, but that makes sense as Nadal is known for hitting a lot of topspin. There must have been at least one rally shown in that video in which the average net clearance was 3 to 6'.
The first rally in that video is more representative of the sort of net clearance I was seeing.
