I know this is super old, and probably no one will reply, but I'm in a slump. I switched over to colemak about 4 months ago, and progress was really fast, and I am now typing at about 70 WPM on average. But that is where it stopped. I have been practicing rigorously throughout the last month and my WPM has changed by maybe 5? Is there any really big thing that you need to think about to "ascend" to the next level? Maybe the "Burst Memory" will help me. I too play the piano and I know what you mean by it, but I feel like sometimes my fingers just aren't confident about a word and then I make a typing error. I am in the process of building a mech, so maybe the tactility and/or clickiness will help, but I really don't know.
