Bingo.

Yes, I realize you can get the SR on the first ticket. You can get it on the 200th ticket. Or you can get it somewhere in between.

The idea is if you get enough data in aggregate, you can start to determine accurate drop percentages. I fed her a BUNCH of r-gachas and got zero SRs. Based on my data, the drop rate is zero. This is clearly not the case. But if you pool data, you will (hopefully) see patterns arise, like relative drop percentages of the other rewards too.
