I swing between 1100 and 900 in chess ratings really obviously. Some days I’ll win and win and win until I’m around 1100; other days I’ll fall and fall until I dip into the 800s. A 200 ELO point difference is equivalent to winning the game 76% of the time, so this means that “best day me” would beat “worst day me” in 76% of head-to-head chess matches.
