I updated the Gatcha calculator based on new data from many hundreds of 10-rolls, enabling me to pin down the category rates for drawing kamihime, kamiless weapons, and eidolons in the SSR rarity tier. This data was collected by retrospectively analyzing the inventories of two whales who'd acquired dozens of SSRs, and then comparing the relative ratio of kamihime, kamiless weapons, and eidolons. This was actually fairly time-consuming since I had to manually image match each weapon with the JP wiki entry and determine if it contained a kamihime or not.

The updated rates for SSRs show that the chances of drawing kamihime in the SSR tier are somewhat lower (~5%) than I'd previously estimated, which is within the expected margin of error for that estimate.
