Just playing around with manually calculating my SAC and comparing it to my Dive Computer's numbers. I've found that the manual calcs invariably come out about 50% higher.
For example on my last dive the SAC reported by my computer was 0.53 but the manual calculations come out 0.72
What might account for such a wide difference?
