Great to see the reports. Maybe a larger sample would tell us more about the "truth".

Luckily all 3 of us witnessed a base rate around 10~12%. With a sample of no more than 200, we may control the error around 4%, with 95% confidence. That would be a fairly solid basis for further testing, I think. (pls ignore the above if it's too intricated.:v )

Currently I'm testing the base rate for #21, it gives me GSc rate of 9.7% out of 124 runs. I'm planning to make it 200 and from which I'm gonna test if FS / fleet level have something to do with GSc rate
