Thank you for this; very interesting & helpful!
By the way, on a totally unrelated point, do Luxire have any plans to travel? I can imagine that the combination of your efficient factory operation, plus the benefit of in-person measurement & fitting, could work very well. Obviously, you'd have to charge a little more for in-person fitting/etc, but it might be worth one of your team crunching the numbers to see whether it's worth it.
I can guarantee you I'll buy a few things if you come to the South-East of England or London!
THIS. (Except swap San Francisco for Blighty...)
