My fingers disappoint me...

Don't quite know. I'm just trying to get to grips with it.
I know it sounds crazy but it really seems like my finger and my mind aren't even connected at times. I see 'A', I'm thinking 'A', so why does my right hand type 'R'?
Even now while typing this... My progress seems to be getting worse rather than better; no matter how much practise.

After getting pretty much no wear with QWERTY for 3 years, I switched to Dvorak. The only one that seemed to make sense with my fingers as I can remember. I can tell you it is does feel so much better but my fingers do tend to feel a bit cramped at times. Much the same like when I was using Colemak. However with Dvorak, my fingers learned the layout so much faster. Within a month I was back to the same point and speed that I was with QWERTY. But does not seem to progress beyond that. Anytime that I think I am, my progress on the training site - keyhero.com shows pretty much that I am loosing control over my own fingers.

Typing for speed, some ebook I read once on typing, recommends breaking down words into single letters.

When you see each word you should visualize the zone where the fingers will go.

Eventually this visualization leaves your mind and is projected onto your fingers.

For Colemak especially, but Dvorak and other optimized layouts too, you can also think about rolls as units.

Rolls can be seen as both (like wave-particles) discrete units and groups of keys.

Again, you should practice with things that are comfortable for you to type, as well as hard.

Varying difficulty for varying speeds. Try to get the hard as fast as the easy, in an attempt to make them all super high.

That's what I meant with the duality of rolls which is how I try to cluster bi and trigrams, followed by same hand. Big reason why Dvorak was weak in my attempt, though its other flaws are also glaring. With same finger, knowing that the same finger will be hauling performance ahead of time is key (pun intended).
