Over a 1 minute period the largest overall deviation is accumulated.
The figures are then stored in 10 minute wide buckets, recording the highest figure for that 10 minute period.
Effectively you get the largest movement in any ten minute period in mG.
The sleep quality is a very simple setup at present:
- Any 10 minute period value above 1000 (ie 1G) is regarded as awake/super restless/being abducted by aliens.
- Similarly a figure around 120 marks the boundary between light and heavy sleep.
The smart alarm averages across the night, and wakes you at the first point between the wake up hours where your movement exceeds average.
