They weight users from different countries by CIA's total numbers of internet users in these countries. (https://www.netmarketshare.com/faq.aspx#Country https://www.netmarketshare.com/faq.aspx#Country ) So some country having a big share of internet users according to CIA and small and volatile number of users counted by Netmarketshare can be the reason. China has about 22% of internet users according to CIA. Is there a way to estimate how many are counted by Netmarketshare?
