A different progressive for every height?

[glasses cheap]

Today I heard a presentation for the new features includes variable height and inset, custom designed for each frame, with heights as low as 11 mm.

I'm assuming this means that for any height and frame size, the add will end up as low in the frame as possible without cutting anything off the bottom, and thus giving the patient the longest possible corridor in any frame chosen. And apparently, it won't be as expensive a lens as you might think. For me, this raises a question: for "low" seg heights (18 and lower) in more conventional designs, should a design be chosen whose "minimum" recommended height is lower than the measured height for the frame? Whichever frame is chosen? THANKS！
