Headtracking - realistic degrees setting?

[Raven Morpheus]

Hello all

I currently use FTNoIR + PS3 Eye + DIY 3 point IR LED clip for headtracking and I have FTNoIR curves for yaw and pitch set to 90 degrees and that seems to work fine, I move my head about 10-20 degrees and the cam in-game only seems to move to the 90 degree point.

I've only just started using FTNoIR with it's point tracking feature, after trying for a long while to get the face tracker to work well and failing, and I was wondering - is 90 degrees movement on yaw too little? Should I be setting more degrees of movement, say like 180, for a better and more realistic view via headtracking?

Thanks in advance.
