Will all this autism about WPM, I'm surprised nobody here has mentioned Plover, Opensteno and other stenography content. That stuff is designed to keep up with real-time speaking in terms of WPM speed. Speaking speed is 220 WPM, some steno typers have even gone up to 300 and above. It's really different though, most of if it is simultaneous keypressing with software interpreting the presses as words, so N-key rollover is important.
Honestly, if you're willing to play with alternative key layouts for faster typing, I think it would be more efficient to learn stenography. But stick to the open-source stuff, professional-tier steno gear is anywhere from hundreds to thousands in costs.
