It's impossible not to have skewed data on here, unless everyone was reporting promptly and data was either recorded on a weekly basis, or each time a new dino was introduced. Obviously, each time a dino is released it changed the probabilities of all the others, and with how often dinos are released it's impossible to keep on top of.

At least going monthly there should be enough data points for accurate-ish results and it's easy to tell which month a dino was introduced and how that would affect all the other probabilites.

I'm curious to see what November holds as well. Also the impact of reduced HH'ing by many users when all the new ghost dinos came out.
