First, thanks for putting this together. I'll contribute as much as I can.

I just want to point out that you're encouraging people to report outliers instead of all of their data. This will skew the overall results due to self-selection bias: anyone who only reports on their really good or really bad pulls will make those results appear more common than they truly are.

Granted there's still value in knowing what the possible outlier results are, but you mention aggregating.

Does the current event impact the available prizes? If you have a max-level limited girl, is it still possible to receive that as a prize?
