I don't really have one either, I think the important thing is to find a good rhythm, and then try to stick to that as much as possible, and only burst when it really is needed. Basically what I try to do for myself is to at least try to keep up with kind of a steady rhythm of typing instead of being all over the place, so mostly I burst through words that I know, and when I come to words that I can't burst I try to keep it coming as steady as possible, if that makes any sense at all.
