I type Dvorak around my old qwerty speed. It’s probably not possible to be faster. For really fast qwerty typists, the brain has multiple fingers with the right hand contortions in motion, hitting keys in order, just in time. Dvorak eliminated hand pain by reducing motion, but it didn’t give my brain the ability to orchestrate my fingers with tighter timing.

The less-movement thing is also why I switched. Wrist pain instantly gone and never returned. Qwerty is torturous.
