Surely. But that assumes they consider the possibility I'm using Dvorak. And if I switch which keyboard layout I'm using it'll help more. (But honestly that's likely to be too much bother and I wouldn't follow through with that practice.)
Sure, that would be an issue. They tend to vary quite a bit more than my regular typing though. And I often go weeks or months without hunt-n-pecking, so it's really not a practiced method with a consistent timing.
