Found the BEAKL / Arensito opposition a bit curious. And the infinite loop at top right :-)

[FWIW, there are various articles on the web about how QWERTY is still the best (for some definition of "Best").]

Everyone in the "Other options available" might feel a bit rejected :-)

As we know, there are a lot of layouts, some get more airtime than others, and I'm not sure why ... I could, for example, argue that HIEAMSTRN should be on there somewhere rather than, say, Norman or Capewell. But Sasha doesn't have a website promoting his layouts.

I suppose it depends on whether you want to include "well-known" or "better" (by some metric. Whole different topic.).

Still, clearly a lot of work and thought went into your chart. Interesting approach. Good job :-)

Cheers, Ian

I feel that there aren't that many top choices, and this chart seems to imply that those are all more or less on equal footing which has to be wrong. If I say that I don't have to have ZXCV in place, I end up with Arensito which just has to be wrong. It is my staunch and firm belief that Colemak is a much better researched and designed layout than a lot of those including ARENSITO, ASSET, BEAKL, Norman and Workman. Pretty much regardless of personal preference, maybe beyond ease of learning for Norman (but you covered that bit with Minimak – skipping Tarmak though).

Saying that you "have to" use RSHTD(?) if you have thumb clusters also looks silly. There's a lot you can do with thumb clusters on most layouts, and back to Colemak it allows you to select pretty freely what to do with such clusters since it's mainly concerned with optimizing the letter block.

Not really, if like me you don't subscribe to the idea of having letters keys on thumbs, then it's a non-starter. The "reference layout" looks way better to me.
