Consensus
With regard to your statement: "Regarding the mediation, this would appear to be a situation of a few editors dissenting with a large consensus. Am I correct about that?" I think it's about right, but does need to be qualified. Some editors, like Matt Britt and Seraphimblade, still do strongly support the binary prefixes (but, to their credit, never edit warred over them). There was, however, an emerging consensus to allow the use of parenthetical disambiguation alongside legacy prefixes, as opposed to replacing them with binary prefixes. I'm convinced a workable solution can be devised if the edit warring stops. In my opinion, Sarenne's role in all this has been highly counterproductive, though I am also guilty to an extent for participating in an ongoing edit war. *** Crotalus ***
