Dunno if the author took this into account, but the fingers that do the work also matter: the index and middle finger are considerably stronger than the ring finger and especially the pinky. See e.g. the Workman layout: https://workmanlayout.org https://workmanlayout.org, and specifically the illustrative picture: https://raw.githubusercontent.com/kdeloach/workman/gh-pages/images/usage-viz-grid2.png https://raw.githubusercontent.com/kdeloach/workman/gh-pages/... This also means that Windows/Linux and especially Emacs users are sorely screwed by the prevalence of the Ctrl key in shortcuts. Somewhat ironically, MS' Natural 4000 keyboard with its gigantic Alt keys is eye-openingly great on MacOS where those keys serve as often-used Cmd, right under the thumbs, the strongest digits. And, when Emacs was created, Control was also under the thumbs. Also, as a bilingual, I'm pining for a design consideration that punctuation is on the same keys between the layouts in different languages.
