How many cubic feet are we starting with and what depth are we starting at?

At 60ft starting at 100cuft you could have 3-5 minutes of air assuming we are talking about the second stage which would be appropriate for a free flowing regulator.

Would you be better dumping your whole regulator and breathing off the bottle by cracking the valve as necessary?
