@Jim D. - I've found that the numbers I get from ProChoc seem to align quite well with those I measure with my Aw meter. The weakness I find with ProChoc is the caramel - I think it's in there but I'm not sure how to account for it. I'd love to be able to put in something like - "X grams of sugar, X grams of cream cooked to X degrees" - without actually having to know the amount of caramel that would result.
