Windows Mixed Reality / HP Reverb G1 height correct. eye level tracking origin?

I calibrated center standing
then put eye level as Tracking Origin
Then start game while standing? If not things dint work

this is using a standard VR pawn with FloatingPawnMovement in it as well for controller input? does that have any influence on height?
also changing pawn height in world no effect
also pawn camera and vr origin in pawn is at z=0

finally it work but is this the best way??
