I decided to give it a go and set up a cronjob which scraped Github statistics every 30 minutes. They fixed it between 1382454005 and 1382455803. Some rows seem to have missing data (I don't know why), so I am not sure whether this is of use to anyone. You can plot some cool graphs if you remove the rows which do not have all (5) columns.
