I have my psi safety margin set to 300 psi so that if in the event that I did something extremely foolish and allowed myself to completely empty my tank on a dive I still have the capacity to ascend at a safe rate and complete any safety stop, then surface with 300 psi still in my tank. I stick to the dive plan and this situation would never intentionally happen and only exists as a safety feature but my question is.....When i am figuring my sac rate for a dive has this 300 psi been somehow subtracted by my computer? When i look at my ending pressure versus my starting pressure should i be adding 300 to get my true sac rate. I probably should have compared my computer to my redundancy pressure gauge to see if there was any difference but alas i did not but certainly will on my next dive.
I welcome any imput.
