You try explaining that to 250 students that can't read what you write. "It'll be ok, my handwriting will improve over time," doesn't exactly fly too well.

Also note that it's pretty hard to give numerical results to a computation on the blackboard. A plot generated by a computer program and embedded on a Beamer slide is optimal in this case.

My handwriting is improving, and I do try to improve. The fact you didn't glean that from my, albeit curt, response is hardly cause for putting words into my mouth. I appreciate the feedback though.
