I started off programming in the actual stops in ProPlanner as a 
multi-level dive, but I later decided to throw in the extra conservatism 
and call it bottom time.  With my history of DCS, as long as I continue 
to be doing decompression dives (I really probably shouldn't), I want to 
throw in extra conservatism wherever I can.  Besides, the time difference 
isn't all that great - what's 15 or 20 minutes in a lifetime? ...especially 
if those 15 or 20 minutes can significantly extend one's lifetime.  My 
belief in the value of deep stops is very strong, so I view them as a 
conservative step to reduce DCS probability. This is what I do and what 
works for me.  Anyone who decides to try the same thing better be ready 
to handle the responsibility for *whatever* consequences result.

Aloha,
Rich
