I thought regions only impact ranking not the net amount of stars (assuming we're talking about Apple/Google Maps). Which as far as I know, github doesn't do ranking. At least on IOS reviews and ratings are by country, I dont actually know about google play though. (I dont have an android to check since I am not poor)
