Viloteau's nail video is one of the first guitar tutorial videos I ever looked at. I'm the guy who linked to his arpeggio video a couple of weeks ago up-thread as a good look at a supinated hand position as well as the alternation of KJ/MJ flexion/extension. You have a point about nail shape. My particular nails/fingers make it tricky to find and keep a shape where the corner of the i nail won't catch if I use a pronated RH. Not an issue w/ supinated RH, and that may be one reason I want to give it a chance.
Add Meng Su to the list of recent competition winners (2015 Parkening Int'l.) who favors a (slightly) supinated RH.
There's been so many posts I can't keep track of who said what anymore, and I'm sure I'm reposting things I already posted. I have the same problem with my nails, in the past I thought it would be best for my hand to play off the extreme left side of the nail with wrist pronation and either file a rounded nail or a heavily ramped nail like Russell does. But this supinated position may be the way to go for me. I was feeling like my a nail was grabbing from the KJ too much, but I think it's because it needs to have a slight reverse ramp shape on the a finger to work at this angle. Once my nails grow out I'm going to try the Thomas V method of sanding but using that supinated position to cut the nail shape.
An eyewitness will often only see what he already believes to be true.
