AWD roller test?

Roller tests of AWD systems started showing up in my YouTube feed so I was wondering if anyone has tested the MS6 AWD on rollers?

A while back I did some searching about the AWD system and came across conflicting information. Here’s a good thread detailing various points of view:

The one by saltytomatoes is interesting (I’ve seen it elsewhere) although I haven’t read anything else from someone who has done actual testing. A lot of the talk seems to be guesses based on some information but not based on actual tests (such as posted by crossbow).

The video linked in that thread is also interesting.

Anyway, I was just curious if anyone here has some additional information.
