That's quite impressive! It is apparent our analysis of GitHub events didn't account for "super-repositories" like this, as this would be the fastest growing repository on GitHub by a large margin, dwarfing large projects like Linux or Gaia (unless Apache or Mozilla also had these super-repositories.) I'm not sure it's quite an apples to apples comparison though xD

On a somewhat related note, another interesting thing to note is that we found apparent discrepancies with GitHub's statistics for contributor counts.

For instance, take a look at this PR: https://github.com/codecombat/codecombat/pull/372

It was clearly merged. Now take a look at the two possible usernames GitHub could have used to tally his contribution: QelioX (his GitHub username) and Esh2349, the username he used on the commit. https://github.com/codecombat/codecombat/commits?author=Esh2... https://github.com/codecombat/codecombat/commits?author=Qeli...

I looked, and I couldn't find anything out of place with his profile. Our method for growth through unique contributors actually handles this case. We didn't have time to explore other properties of the GitHub data set which might throw our analysis off, but hopefully someone in the future will produce a nifty analysis which does account for them.
