I though Hyper manual gave you a one time auto-reading, (in the *ist-d
changing both Shutter and aperture according to the program line),
whereas Av, (Aperture preferred automation), continuously updates the
shutter speed based on the current aperture, lighting conditions, and
correction factor. They are two similar, (in that the camera chooses
the exposure), but different things.

Where have you seen this "aperture preferred automatic" term? What
you are describing above is the behaviour of Hyper-Manual mode, as
defined in the Z-1p manual.
Long before there was a PZ-1 there was a camera called the ES, the
first aperture preferred automatic camera to be exported from Japan
I heard the term in 1971, when I saw an advert for the ES
Pentax coined the term "Hyper-Manual" to describe going from manual
exposure to automatic exposure by pressing one button, rather than
having to turn a dial, or change a menu setting to get an automatic
exposure quickly.
Call it what you will, if the user sets one exposure parameter and the
camera sets the other one, it's auto exposure.
