I test around 80 WPM at the moment, but I was able to grind out 104 WPM on a typing competition by gradually upping my speed using a metronome.
However, this prompted an anticheat test to evaluate my results. It seems like the anticheat reads individual character strokes, since it consistently says I typed zero words correctly, and stenotype involves keying entire words/syllables at one time.
I'm not super let down about not placing as highly in the competition as I would have, since I'm mostly concerned with reaching higher speeds just for my own improvement. But competition is great motivation, and I'm hoping that there could be a workaround for this in the future for fellow aspiring stenotypists.
