I see no reason to believe that, given his process for ripping an "equal" number of commit messages per language was broken, that anything else even approaches validity. It's simple arithmetic; a grade schooler who notices that the last number is 7 would realize something's off.
What about the process is broken? Did you read the code and find bugs? With a total commit count of 929857 missing a single commit to round out to a perfectly even number of commits in each language is insignificant.
