Substitution chart how exact is it?

No substitution chart is going to be perfect. One thing I noticed on this one that I disagree with is using 1 cup pancake mix for 1 cup baking mix. I think of Bisquick (baking mix) as having a lot more rising properties than pancake mix would have. I also disagree with some of the other substitutions as far as whether I'd like the end result if I used their substitute, but the quantities look ok.
