We’re working with a very small data set right now. I recorded over 150 community drops and it seemed somewhat evenly distributed. I haven’t updated it in ages though.
It’s very easy to get frustrated by inconsistent drops, and that’s fine. But as far as I’m aware, there is no collection of data points larger than the sample I collected in the linked thread (if someone has a larger collection I’d love to see it though!). The data does not reveal any notable inconsistency. RNG can be rough 
If someone wants to continue my chart, go for it. It got messy to track in the thread.
