Writing by hand slower by the hour, more by the week?

My goal is to get my handwritten daily word count up to what I can do on a slow day typing. I can get around 350 words written in a half hour. That isn't a bad rate, when I'm not distracted. My goal is to double that. 700 words an hour is pretty good. Two hours of dedicated, undisturbed, and not distracted writing time could get me to where a manuscript would be complete in a month or two. The trick is managing to hit that consistently.

I am trying to approach this like spinning by hand. Spin when I have the opportunity and I'll manage a mile of thread by the end of the month. Write when I have the chance, I'll manage a novel length manuscript by the end of the month.
