AeroPod, PowerPod and Newton

I recently updated my PowerPod Lite, from Fireware 640 to 641. Started a calibration ride, and noticed it no longer does the new O&B cal ride. It does the 0-100 calibration. Not the 0-50, stop , turn around and ride back 50-100. It's not a problem , but wonder why , or is this now the type of ca...

1) You don't have to use a spirit level. PP auto calibrates itself to within 0.05% 2) When you move from bike to bike, both wind and tilt can change. So yes, spend the 5 minutes required to do a new calibration! 3) If you use the same sensors on both bikes that's OK, except the automatic profiling ...

Thank you, very helpful. Can't wait to take this out for a test ride. Weather is the issue now. I have installed Isaac software, and will spend time playing around.

Regarding calibration, I'm using the same Garmin, speed , cadence, HR monitor. I also use a spirit level, to ensure the unit is level (placing level under "PowerPod" letters).

So, when I transfer all this devices to another bike, is O&B calibration required ?

Thanks
