from there you should be fine, just need to practice more for speed. i have had a few layouts learned to about 40-90wpm on a regular keyboard, two on a characorder to 40-60wpm, and can fingerspell 20-25wpm w/ steno. learning a new layout is not that bad, it just feels weird for about a week, and you need to put in 15-20 hours on a typing site/app, practice everyday, and sleep on it. it one of those things where you don’t see the gains until the next day or two. the charachorder took a little longer at first, but that was because you also have to learn the charachorder too. at 25 wpm you would be mostly building speed which is layout independent.
that would make sense. i have had some issues too, only had to send one unit back though, which was why I think this may be better. i mostly use mine for some games and a macropad basically. i like the idea but am wondering about the long term reliability.
