I think that's the rub; the VR industry is running into a similar issue that the Headphones industry has long dealt with, the reality of different body dimensions. 1 isn't an issue for me thanks to an improved strap, 2 isn't an issue due to, I think, my move to a rubber face wrap, 3 again was fixed with a new strap (though it just comes up onto my forehead rather than tilting), but 4 is the hell that I cannot think of an answer for. I may not have the issue, and maybe that's due to my prescription inserts or maybe it's due to the particular shape to my skull.
