Thanks! As I've been creating other examples (yet to be released), I've discovered there are always going to be little quirks with the way you want certain data pre-filtered or grouped, aggregated and then grouped again. But in general my time creating my first board went from two weeks (http://stonefinch.com/Projects/Medicare - 19mb download, it'll take a while), down to 1-2 days, then down to 4 hours. Now with machete I can knock out a new board in less than an hour. I typically spend a lot more time just munging together data.
