I have heard Stages combines the accelerometer readings with looking for power pulses (similar to power tap indirect cadence) to smooth out false readings from bumpy roads. If he power is really 0 then cadence is not so important at least from a power meter perspective. I suspect that power2max may be doing something similar. Quarq (new ones) and Garmin vector use the same accelerometer cadence detection so it would be interesting to see what they come up with.
If it is just the cadence at 0 watts then a cadence/speed pickup would solve it. Null data is more of an issue if it there is force and rotation so you miss real data.
I am playing with a power2max on the trainer so can see if rotation with no power registers.
