You are aiming too high, I think. While all this might make the difference between two champs with equal skills, I think it is a limited gain in the end compared to lots of training. Work, work, work, and gain 10wpm in a few months. There is no quick success. Or you need a new paradigm, like typing in syllables or popular words using macros, which is not cheating like in macroing parts of a text, but changing the atomic unit. Consider Japanese, where the syllable is the atomic unit, which is actually quite smart and effective.
I still don't think using macros is fair. I don't see improving much past 110 wpm without changing the board or format I'm typing on. I've shown that key type can make as much as a 10-20 wpm difference in raw speed now. It's possible that a board could make as much as 30 wpm difference.
I'm typing as fast as I can on one phrase to get that result. I doubt much more training with the boards I have now is going to make much of a difference to that speed. I think there is a max speed to a board switch/cap type, just like a car. It'd be better to find a board that has the highest max speed, and then work like hell on that to max out its speed. It's kind of like you're saying, take this vw bug, and train on a track to get it up to 200wpm, it's just not going to happen. You need a combination of a well performing high speed car, and a skilled driver to get those results.
If you told me what board the current record holder of 309 wpm used, and he was actually typing real phrases like on the typrx website, not using macros, then I'd be satisfied with that, I'd buy that board and train on that, but lacking that information I'm going to try to build a board with the max possible relative speed.
I'm viewing this a lot like nascar, or f1, where new devices are thought of to improve driving for everyone. I've already hit on an invention of using silicone just for normal keycaps that I plan to use in the future. A lot of this is producing results that's useful in just normal typing.
The Japanese example doesn't track. Those are actually letters, and they're not all syllables in fact. They have vowel sounds and modification symbols, and one consonant n, that effectively turn the raw consonant/vowel combination into more consonants which doesn't follow exactly for syllables. Even if you're talking kanji, a lot of characters are still just a single vowel sound, which isn't a syllable when used in combination with other letters. At any rate you're talking about a different language with completely different sentence and word structure in general. Words sound completely different to what would be made with a Latin based language. It's so different you can't even count wpm when you're talking about Chinese or Japanese as a source of comparison, you have to talk in cpm purely to have any comparison at all.
You're saying that I should come up with a new English typing format completely essentially. That would take a lot of work just by itself.
It's actually probable that this has been done hasn't it? I think it would still be disqualified in a competition situation since it would take alternate drivers or macros to run on the computer.
