If I invert the pitch or yaw axis then instead of looking left when i look up it looks right instead. ect.
Inverting pitch only inverts pitch, likewise for yaw, inversion can't change pitching to yawing or vice versa.
Everything looks just like all the other 3 point models. That is why I am so lost as far as why i must move the middle point even with the other 2 for it to correct the axis.
Most people have their webcam at head height, this is what FreeTrack was designed for, having your webcam 2 feet higher is very significant (especially for 3p cap) because it changes the way the point model appears. You could try to get FreeTrack working when the webcam is at normal head height before trying to push the boundaries of the tracking algorithms with a higher camera position.
Naturally, a higher camera means the model plane is more likely to be parallel to the camera plane, which is bad. To avoid this the middle point should be lowered as much as possible so long as it remains the
highest point in the camera frame for all possible head orientations.
