There is a simple formula for the difference in the rating when we expect 14.5:3.5 400*(14.5-3.5)/(14.5+3.5)=4400/18=244.444444444444444444444444444444444 There are infinite number of 4's but unfortunately this post is too short to include them. The formula is also not exactly correct but only close to be correct. The performance of Junior6 based on this formula is close to 2750 when I expect ssdf rating of only something close to 2700 so Junior6 is probably earning some rating points from these games. Uri
