emWave Handheld Device Accumulating Score Time ProcessAug 09, 2018
(This reflects a 5 breath per minute protocol.)
That's the amount of time for the Breath Pacer to make one complete cycle and compile the information required to post the accumulation in the Heart Action Strip by adding a light.
Consequently, it's approx. 2.8 minutes to completely fill the Strip with the accumulated coherence score.
Once the Heart Action Strip has been filled with accumulated lights, the unit will clear them all and put a brighter light at the bottom.
This indicates that you have one full cycle accomplished and are beginning on the next one.
