I had trouble with the controls while I was using a 3rd party sensor bar. It would shut off if inactive for a period of time, something I thought wouldn't matter since the game doesn't use IR. However, I realized that when I made sure the sensor bar was turned on, the controls were pitch perfect and I never had to re-calibrate. Thus, I searched veraciously for my original sensor bar that never turned off, and once I found it I never had any issues with the controls for the rest of my 40 hour journey. I don't know if this could be applicable to you, but I'd check your sensor bar, since it made a huge impact on my experience. I was hugely frustrated with the constant re-calibrations until I figured this out.
