Oh sorry, Yes ! That's what i understand now through your complex discussion. That's defenetly right.
Yes yes yes, it is just an other way to make an SRT. My bad.
OK so what happens with the "frenchy" :
Ascending it's an SRT.s
Descending or limb walking it's a SRT.d
Adding a third prusik as it is made for, it became a DRT.dd or DRT.sd, can even do a DRT.ss
...
So there's no way this technic can be called with new acronyms. We got to stick on the frenchy stuff.
Other statement leading me to my point :
In France we love a lot using belays for recreation. I think it can be right on US soil too.
Belay is SRT, plus it is dynamic. So it is a SRT.d. What's de différence is the DdRT becoming a SRT.d too ? Number of persons, so we should say SRT.d1 for DdRT and SRT.d2 for belay.
Except it is not necessary because everyone knows what a belay is.
So here's the idea, SRT DRT .d .s / whatever, all these are only technical acronyms made to define precisly how things work. The more complex it gets the less people can use it. But they can easily understand what they are talking about if they use commun words such as belay or frenchy.
Problem DdRT has no equivalent in simple words. So if this classical acronym is no longer good to the point it has to be changed and the new one to complex you should find commun words to give a name to it. SOme time we say "auto belay" in France, because it is what it is...
PS: by the way SRT isn't forbidden in France, non EN standardized tools are forbidden, that's a different problem. And as we don't have efficient EN SRT.s tools (who would like to do tree works with a Petzl I'D ?...) we use SRT.d1... as it allows us to have good tools like friction hitches.
