The topic came up in a discussion with a tech rep some time ago. The discussion had veered off the main topic at that point so I didn't pursue it any further.
Thinking about it a bit more, 10 000 ft/min seems a bit low as a cut-off value. I would expect the IRs to be able to provide valid data at higher vertical speeds.
With regards to the PF and the V/S display, there are two slighly different layouts of the display. One where the only visible part of the pointer is the one covering the V/S scale, and one where the full lenght of the pointer is visible.
I do not know which version AF has, but if it is the first one the position of the pointer is less obvious when pegged at one end of the scale.
