Uhm...In the table you provided, I see a total drop of about 7% for the latest step and 8% for the step before, with an even bigger drop off before that. I don't see any exceptional outlier at the latest step, but maybe I'm just blind.
In the census, the biggest total player drop is at 3.3 with 78350 difference. The biggest drop before that is between 2.55 and 3.0c at 61444.
In the table you provided, the difference is 13% for 2.55-3.0c and only 7% for 3.1-3.2. It's rather hard to compare since one is total numbers and the other percentages, but yeah...
(*Does some quick math*)
Okay. About 44% clear for 3.3. About 60% clear for 3.2. 63% for 3.1. It's even worse in percentages... don't do percentages people!
