Max, if it's fine tuning you're talking about, I'm not sure that you could see in a video the difference of moving the bindings a 1/2 cm forward or back.  Boot forward lean and ramp angle, OTOH, are things that would probably show up in video very nicely, as they have a more pronounced affect on stance.  But small movements in binding position, as they don't affect stance as dramatically, I think you would have to go on feel rather than visuals.

To your earlier question about trying to understand the BOF-CRS equation, here are some tech articles written by Lou Rosenfeld, one of the Boot Guys on Epic.  There are at least three articles on this subject, plus other good stuff on ramp angle, boot fitting, etc.

This one is particularly good:

Hope you find them informative.
