I can see your point, although Dvorak was also designed to maximise the back and forth between 2 hands, for typing speed, and that could actually have a positive impact for precision when the whole word is being taken into account. Most typing with thumbs on small screens relies heavily on autocorrect in that way, so I can imagine that Dvorak might provide more information for that to work, even if each character might be less precise by itself.
