I don't have your prog, but looking from your screenshot, you don't have a way to input/change the lvls of the fodders you use for accs? If you actually want to have a useful accessory lvl'ing calc, you're going to want that. You can use this table if you want the amounts each acc at each lvl gives as a fodder too.
The left side is different element accs, and the right side is from same element accs:
So if you actually get a working acc exp calculator, I might check it out then.
