In regards to typos such as "teh/the" and "form/from" mentioned above I have noticed a pattern to my mistakes. I tend to make these mistakes with letters that are typed with different hands. For example my left hand will hit "t" and then "e" before my right hand hits "h". I am particularly horrible at hitting the letter "a" too soon. I have also noticed that I rarely hit letters early with my right hand.

Strange that my left hand gets ahead of my right hand so often as I am a righty.
