Field notes
The trainer organizes practice into numbered placement modules, beginning with home-row technique and progressing after a module is passed. Its result screen exposes more than speed and accuracy: it reports rollover, hand-to-hand transition timing, steadiness, and wrong-key counts, while distinguishing errors left uncorrected from every incorrect keystroke. The page cautions that browser timing has millisecond-level limits and that one short test is only a small sample.
