Pebble Vs Bangle

It is tempting to think that its just a case of incrementing the RWA_THRESHOLD to 15 but we should understand whats gone on here in terms of the variation on accelerometers.

Maybe we could introduce a calibration phase of some decription.
The idea behind the gated code was to stop just raw noise being looked at.
My observations did see that there was usually more positive noise than negative in the signal.
Needs thinkng about.
