Not shockingly the rating and ranking of the people who went 7-7 is very similar to their starting values. For instance, Reid’s 7-7 changed his rating by 1.97 points (from 2068.35 to 2070.32) and his ranking from #19 to #20. Less obviously, Elo was not impressed by Blohon going 9-5. Given his schedule (i.e., that he played a player ranked 2066, then a player rated 2026, etc.), a correctly-rated 2320 should have won about 8.65 of their matches. So this was a slight overperformance in the system’s eyes, hence a slight improvement to his record — he ascended from 2320 to 2332. Similarly, Niels performed shockingly close to expectation: his rating moved by only 0.75! He went from 1716.30 to 1715.65, a change small enough to be swallowed up by rounding. Again, the bulge of people in the low 1700s still meant that he was passed by twleve people.
