The angle, in which you would move your head with TrackIR, is only just the angle between
looking from the left edge of your screen to it's right edge.
Within that angle, you will receive the view from forward to check-six left or check-six right.
The speed, in which the view will change, can be adjusted.

which happens easisly due to the emotional stress during a dogfight.
If you think you can make the movement from left to right edge of the screen more often
(without doing that too hard, or tensed up), without getting a pain, then you could try it.
