That works. I agree. If you do something stupid, ignore your computer, use every last second on no doco time, assend quickly... your computer will not save you. I am surprised at how many people dive and have no clue what their computer is telling them (beep, beep, beep). I asked sometimes why their computer is always beeping and ths best response I got was "it always does that!.I believe it is. Just did a check. 2007. Only 42 dives on it. $40 US. Can't go wrong. Expensive computers don't stop you from getting DCS. Plus, if you lose it, there's a good chance you won't get it back. What do you think of my bungee straps?
