You are always going on about the GUE crowd recommending RD as a panacea without explaining the limitations/risks. We counter it by saying that you really need to know the whole picture about doing RD (mixes, ascent rates, deco gases etc). Please do not undertake RD unless you have a good idea of everything that goes into RD.
In your case videogirl, I would recommend using a bottom timer and tables to start with (as that is what you are going to do on the course) and then once you have an idea about where you are going in deco diving, then choose a computer to match your aspirations ie single gas, 2 gas or a full blown VR3.

There is no diference running ratio deco to running any other sort of deco?
ALL deco is mix dependent and ascent rate dependent. Standard safety procedures like planning the deco bassed on max dpth as you do with tables are directly transferable to Ratio Deco. Standard deco gases are prefered but not esential
My point being in the 40-55m range 1:1 ratio deco with a single deco gas of 50% is simple and has very few problems of note.
Beyound 55m it gets a fair bit more complicated and can be problematic in terms of levels of agression.
I beleive your confusing my opinions on some of the dive planning systems used with "deco on the fly" as outlined by an number of GUE divers. I dont beleive this has any relevence to divers using ratio deco.
I use ratio deco and i dont folow those planning ideas and I dont use standard gases.
It still works, but my ratio deco profiles are likley to be a lot more conservitave than yours.
