You should recalculate the profile by adding short >(2-minute) stops at 200 feet, 150 feet, and 125 feet.

Plus the extra hang time will probably help reduce DCI. Another method I have used is to look at total time to surface upon leaving the bottom, add the deep stops, then use the computer as a timer from there sticking to the total ascent time you got and doing the rest in your head - last few times I used that Fibonaci thing George mentioned. This works fine with my Alladin pro for ocean dives on air. What is DCI anyway- I dived with some guys this weekend who wore no BC and only singles, did 16 mins at 200ft and then only 15 - 20 mins deco(with deep stops)and only 2 bends symptoms out of 10 dives. Stupid safety conscious me dived with twins, did 25 at 200 and lots more deco than them. > > >>And I do not like the idea of altering a schedule form an artificial insertion. > >Why not?
