I’m truly very happy to hear that you found a tool which helps you!
Just keep in mind to be focussing extremely and solely on accuracy, no speeding, no bursting.
Drill the keys, the rest happens by itself.
(Up to a speed where you can comforatbly type. Then and only after that, come the specialized trainings for 2/3/n-grams, burstings, read-aheads, finger swaps, etc. - but you need an extremely solid basis for that, where even complicated words just flow out of you without any thinking. Pace yourself, get to at least a constant and repeatable 60 wpm with 99,5+% accuracy on a bad day first before going further)
