Help! Google and Wikipedia haven't been too helpful here. I'm looking for a good program to practice 10-key on.

I've been using gtypist for 10-key, and while it's a great program for QWERTY, the 10-key kind of sucks. For one thing, it measures speed in WPM (words per minute), while my temp agency measures it in KPH (keystrokes per hour). I believe this is the standard, because "words" doesn't really make any sense for 10-key. I looked through the man pages, and it doesn't look like there's any option to change this. (Also, the lessons are kind of sparse...there's only 3 for 10-key.)

I know there's websites out where you can practice 10-key, but I would prefer a simple, command-line program like gtypist. There's a job offer coming up in a few weeks, and I was told I'd have a better chance of getting it if my speed's up around 10,000 kph.
