With pure Buhlmann ZHL-16b and no deep stops you get 45 minutes of deco,
starting at 70 feet.  The total run time is 80 minutes.  You can get the
deco time down to 35 minutes if you use optimum gases for each stop (i.e.
CCR@1.6).  Not that I advise that.  I just thought the pure Buhlmann example
would supplement the discussion.  Personally, I would take about an hour to
do the deco, starting at 150, a long stop at 20 on O2, and then a 5-10
minute ascent to the surface.

If DecoPlan is based on ZHL-16b (just for the shape, I presume) then how
does it differ?  I assume that it has special deep stop calculations and
those deep stops to not contribute to the gas loading.  And the M-value
supersaturation gradients are customizable.  Is that it?

The web page to DecoPlan says it handles repetitive dives and penalizes
subsequent dives, but I've seen George III say recently that repetitive
dives are not affected.  I'm a bit confused by this.

And just to be clear, I am not attacking DecoPlan in any way.  I've
personally implemented ZHL-16b w/ Baker's "gradient factor" and having done
so I am simply curious as to how DecoPlan differs from this.

I think that what everyone is looking for here is more
quantitative/mechanical information on how to calculate profiles the way the
WKPP/GUE guys do.  If this is proprietary information then I apologize for
asking.
