While I do agree that the 5* potential rate is around 10% and your post results shows that too, we should still take this thread as biased. It's such a small poll, I saw some people posting some time ago on a collaborative effort, and even then, with low data we can't assume anything, so, please, have precautions when making assumptions
Besides, we can't only compare your results from time to time as all Mobile Companies keeps changing their summon rates from time to time, be it for an event or a promotion of some sort.
Maybe it's best to make a community effort again, and even then it's hard to take it all without any bias, some people like to post good results while some others only like to post bad results.
I agree that the current results are perhaps very inaccurate. However, this is just the beginning. Let's say that for the next event of perhaps 14 days, I do another 14 draws. That could up the sample size to 280.
However, like you mentioned, perhaps with each event, the rates change. Well, to that, all I have to say is we will have to see about that. I mean if I consistently get a 1.3% new event summon rate for the next 2 events, we can maybe, just maybe assume that we are on the right track. Once is an incident, twice a coincidence, third time is a pattern. Worst come to worst, the draws between each event vary a lot and we will just settle for an inconclusive result. Looking forward to the draws of the next event. Stay tuned!
