Yeah, that's pretty close. Decom uses a straight Buhlmann - it's a good package. The figures between two implementations will never match up perfectly. This has to do with sample rates, calculation of ascent/descent rate, and how ascent rates are factored into stops. -Will On Tue, 25 Nov 1997, Jon Breazile wrote: > William M.
