How fast can I type? Well, I can tell you. 43 words per minute, according to Mavis Bacon Typing Tutor. My employer allowed me to download this and give it a shot as part of my training.
A couple of years ago, outside of work, I spent a couple of months learning touch typing using Klavaro, another free package. At that time, my PB was 40.9, so before this project even started, I smashed it. Now my intention is to go back to Klavaro and just to beat 43.0. How long will it take just to nudge this up? Maybe only a day. We will see.
