By that definition every throw is a calibration throw then. Only the pointing to establish the reference point before each action is really calibration, and it's disguised well enough to be pretty seamless anyway so I don't see it as being an issue, at least in Tiger Woods and Wii Sports Resort. (Didn't notice it in Grand Slam Tennis either but that doesn't try to reproduce 1:1 motion.)
