Question on Drop Rate

Guesstimating, you need to do this 100 times just to beat the variance, before factoring the difference between the two drop rates. We can consider based on sum of quills, or we can consider based on individual data points. But lets come to that after more people help us out.

Unfortunately I think the quills will stop dropping today or tomorrow.
At 10 runs a day it will be hard to get 100 runs (per drop-buff configuration, at that) of any event drop, unless we can get a lot of people helping. Which nobody but tecul1 seems inclined to do.

Must find some other consistent scenario that can be repeated more often.
