How does Tracker handle multiple calibrations? Last one wins? First one wins? Averaging?

Thanks!

Last one adjusted wins.  Try making two calibration sticks, leave both visible, and adjust one.  You'll see the other one adjusts itself in response.

Basically, every calibration object adjusts the underlying coordinate system and knows nothing about the other calibration objects. Then all calibration objects draw themselves according to the (changed) coordinate system.
