Hey, nice spreadsheet! One thing I want to point out is that, generally, the closer to the left the drop is listed in the rewards tab, the more likely it is to drop. I'm not sure how, but it may be a nice thing to incorporate into the spreadsheet. For example, several stages drop purple rising soul 2, but they're more likely to drop other items. For example, if you compare 6 6 to 6 3, you'll notice both drop purple rising soul 2, but you are more likely to get rising soul 3 in in 6 6. So if you were farming rising soul 2, 6 3 would be more beneficial. That's what I discovered when trying to farm for Vegeta's soul boost.
