Understanding FOV and its variations in Pimax headsets

Okay but rendered FoV is fixed and we know for fact pimax made errors calculating P2 series FoV in terms of Hfov which maxes out at 160 wide.

Now hopefully this is not trying to bypass the question why the Crystal from chinese testers that have ran @risa2000 Hmdq tool which collects driver data. In that test it clearly shows the Crystal requesting a FoV to be rendered 103° × 103° with a diagonal around 120ish. So during that published test the Crystal can only display a total FoV of 103 x 103. Is that maybe the 42ppd lenses running small?

It is only hard to measure perceived FoV which cannot be greater than what is rendered. Which is true of all vr hmds. You cannot see more than what is there.
