Maintaining same coordinate system between controller calibrations about moveme HOT 3 OPEN

Unfortunately not easily. The coordinate systems should converge over time 
(Move is always trying to compute the true coordinate frame) but will not be 
the same immediately.

Thanks for the clarification. Now I'm trying to figure out when the coordinate 
system is converged while waving the controller around; Are there any other 
parameters besides camera pitch angle that I should keep my eye on?

The yaw angle of the Move controller should get better over time as well. 

To get the best initial coordinate system, when calibrating the controller must 
be pointed directly at the PS Eye. If it's pointed off to the side or above or 
below the camera's lens the initial guess will be worse.
