I'm doing my best to switch to Colemak. This means wasting my time on typing tutorials. I've started to think about typing tutorials in general, and I would like to bounce some ideas off keyboard enthusiasts (you).
1. Colemak tutorial in "gtypist" is too short, after a few repetitions, but well before I develop new "muscie memory", it gets boring.
2. Lists of words and N-grams frequency in English language are available on the Internet.
3. Computers are fast enough to measure not only how many mistakes I make, but also how long I hesitate before keying each letter (and how letter sequence alters my lag).
4. Data gathered by analysing my typing, correlated with 3-gram frequency data, can be used to predict which of my weak points will slow my typing down the most, and focus training on them.
5. Frequency lists can be used to create typing drills (selection of words or 3-grams, composed from "known" letters, randomly chosen, with frequency as weight).
Do you know of any typing tutorial working in similar way?
