We've kicked this around before, and I am the outlier, so I'm asking again.
If someone is hyperopic, they will experience BU effect to a variable degree on downgaze.
Say, +10.00
Say, 1mm downzage = 1^ BU
2 mm = 2 BU
3 mm = 3 BU
So the lens is a gradient prism:
zero @ straight-ahead gaze
1^
2^
3^
4^
5^
6^
7^
8^
9^
10^ @ 10mm downgaze.
So the perception of objects' location in space is
correct
lower
lower-lower
lower-lower-lower
lower-lower-lower-lower
etc.
This will mean that, standing, one's dance partner's face is in the right position, their waist is rather low for a person whom you are wrapping your arms around, and their feet on the floor are really down there. The person is optically stretched downwards. This is why people get sick with glasses at first.
Now, lets talk about progressive zones. The view of the bottom of reading material through lower part of the progressive is perceived lower than the view of the upper portion of the reading material.
So, it makes sense to me that one would want to accelerate the progressive corridor's rate of change and get to the stabilized near zone more quickly so that the view would become more compacted.
I am a blithering myope so I cannot test this theory, except in reverse.
Any real-world wearing experience, here? Any theoretical answers from ray-tracing savants?
