Do DOTF or other systems have fast 10-18m/ min ascent rates to the first stop depth and is there any one out there using this method (or something similar) that has experimented with it.
It would be interesting to here some more about it.

Hi Mark
Yes Ratio Deco has variables based on gas mixes depths and times, all very much of a muchness really.
Tech 1 depths and gasses have one variable, in Tech 2 theres another.
Remember though, they
only work with GUE standard mixes and dive profiles, by that I mean someone who may be diving a "best mix" for their depth followed by an 80/20 deco gas or whatever, they then should be aware that even if they are in full knowledge of all of the sums, they are working outside of recognised GUE tried and tested parameters and are probably going to end up in a world of pain.
As far as ascent rates are concerned its 10m a minute up to the first deep stop and then 3m a minute thereafter
