I think it's pointless ignoring the written articles for the sake of the video. Absorb it all, I say. The most curious thing for me is the balancing act involving chairs / cushions and the proximity of the chairs to the entrance.
Personally, I think all those points are exaggerated and can be debunked quite easily, Roch.
Firstly there is no balancing act going on with one chair supporting another and so on, Nevill is sitting on 'one' chair and his weight is holding it firmly in place without the need for any other help.
I have said it before, Nevill is supported by the upturned chair and scuttle, but also the wall, which he may be leaning into ever so slightly.
Those are the three things that are supporting Nevill and no other help is needed from extra chairs or anything else as far as I can see.
Also, he has one leg forward and one leg back, also helping to stabilize his stance.
Infact, I believe his pyjama bottoms being pulled down and stretched also help.
But! Thats just my opinion, Roch.
As for this 4 inch gap to squeeze by, that just isn't true!
The kitchen door can be opened well round because of the recess before the chair hinders it.
If you do a quick sketch with a scale ruler you will find the gap is nearer to 18inches and not 4.
Yes, you may have to squeeze past the second chair or step over it, but this wouldn't be hard to do surely?
Anyway, thats my opinion!
