I can understand wanting to get as much diving in as possible, but 6am-8pm seems rather excessive. Four to five hour long dives a day is plenty. Also that includes some shallow (10-30foot) dives.

Read all the posts ..... initially I was using multilevels dive profiles (square root shaped) and did not see any deco violation (but still saw high Nitorgen loading % - and I was NOT cool about them).
Then I was asked to check the sequence for square profiles ... and - as expected - the loading numbers went through the roof.
Small changes in the profiles of the individual dives could make a substantial difference. Of course this is all theory
The lead compartment is usually defined as the compartment with the highest normalized level of nitrogen loadingNot sure what you mean by "Lead is the slowest compartment?
A profile that looks like the square root symbol used in mathThanks! What is square root shaping of a dive profile? I've never heard of that?

I've been on boats that ran 5 dives a day - 2 morning, 2 afternoon, and 1 night - for several days running. I don't do them all 'cause I'm too old and lazy, but many of the young tigers did, and on air, too. I like Nitrox on those multi-day deals.
I guess the thing that puzzles me is this: We have a scenario here (4 days x 24 dives) that your dive computer will let you do, but will get you bent, and nobody seems to have a definitive answer for. If 4x24 is bad, and 4x15 is okay, then where is the line?
If I am not mistaken RGBM and DSAT algorithms have indeed a max half-time of 480 minutes, but, all the algorithms based on Buhlmann ZH-L16 (or including some portion of it - such as VPM and Z+) have compartments with much longer half times (635 minutes)I believe the problem is that most dive computers do not use as many compartments nor such long half-life compartments as the algorithm in DiveNav's simulation. My Oceanic uses 12 compartments with the slowest compartment being 480 minutes. As I recall the 16th compartment in the eDive simulation is something like 680 minutes...... .
