I can type rapidly with ease, with peaks of 100 wpm, and 70-80 sustained. However, I'm a bit clumsy and miskey often, dropping my adjusted wpm to 55-70 sustained depending on the words involved.
I know I've miskeyed even before I see the wrong letter appear on the screen, but I can't help it =\
The sad thing is, I nearly failed typing courses back in school. The testing system was rigged against me, in a sense. The letters and words would lock in immediately, making typo corrections impossible, significantly dropping my typing accuracy and distressing me. I absolutely hated seeing a red mispelled word among black ones. (Which is how the program worked.)
Working with more flexible typing tests, my scores improved drastically. It just goes to show you how important method of testing can be.
While typing, I don't think about it at all. Whether writing from my mind, dictation, or copying a document verbatim, it translates directly to action. Typing feels a lot like playing an instrument to me, in a sense. Just with letters instead of notes.
