I like the fact that you thought of providing a method to put in the mold size and calculate the size of the batch but, it doesn't appear to be working right now. I have some new molds (10 X 3.4 X 2.5) and put in the size. The calculator correctly calculated the batch size as 34 oz. (963.88 gms) but, it didn't use that to size the recipe. It sized the recipe at 663.49 gms.
