This article doesn't actually support the claim that D'Nealian is faster than cursive. It just states the claim, without any references. D'Nealian is intended as a teaching script, so the claim is dubious to me. That said, I definitely don't write in stereotypical looped cursive. I remember that I did learn D'Nealian in school, and my handwriting today is something like a hybrid. The main improvement in speed for me came from the ability to write entire words in a single flowing hand motion, rather than having to pick up the pen repeatedly between letters. Cursive provides a consistent method for doing that.
