I've edited the Swordmaster Guide exactly twice, to fix glaring errors. I don't edit it because (A) it has deep structural problems that require a rewrite, (B) I would rewrite it to match my own sword guide of course, and (C) then we would no longer have two independent sources of opinion on this topic. Ideally, some knowledgeable, thoughtful sworders with viewpoints different from mine would improve that thing to the point where it deserves its pseudo-official status.
Edit: At the risk of self-aggrandizing: I wouldn't mind turning over my guide to the community, by replacing the Swordmaster Guide with it. But then we're giving up on two independent sources.
