12 mins on 6 mins off. Helps cool down the lungs as high (1.6 ppo2) o2 exposure can "fry" the alveoli in the lungs causing vasoconstriction .
With a 20 min 6m stop break it into 2 x 10 min with a break in the middle.

Jack, given your example are you not counting the break time as part of the deco time?

Thanks
