These screen shots of the Inner Balance session screen at the four different challenge levels show how the thresholds between the low -1, medium -2, high -3 and highest – 4 challenge levels increase as you change the challenge levels from one to four. Note the differences in the Coherence Over Time graphic.
The coherence score ranges from 0 (no coherence) to 16 (theoretical maximum coherence) and is independent of challenge level.
There is a 15% higher degree of difficulty in getting into and sustaining High Coherence between each of the challenge levels – 1, 2, and 3. Between levels 3 and 4, that increases to 30%.
The low/medium threshold goes from 0.5 to 0.6 to 0.6 to 2.1 as you raise the challenge level.
The high/highest threshold goes from 1.8 to 4.0 to 4.0 to 6.0 as you raise the challenge level.
