I have bought a Basis Peak and have been tracking my sleep for a week now. The device provides you with a breakdown of the total number of hours you spend sleeping in REM, Light and Deep Sleep.
It also provides you with a sleeping score which however accounts for the number of hours spent in each state (ie: if you spend more hours in bed, the score is higher).
Since my objective is to spend less time sleeping but spend it in the best phase (deep), then I would like to come up with a score formula which gives deep sleep its due weight. Once I have this in hand, I can experiment with various supplements such as ZMA, L-Try, L-Taurine etc and see whatever results in significant changes.
Anyone can post feedback or ideas or thought on this line of thinking?
