I thought you had a great summary in the first paragraph but I think you lost it in the 2nd one. In 2022, the White Sox finished 15-17 against the East, 37-39 w Central, 18-16 w West and 11-9 against inter-league. So in 2022, they basically finished within a game of .500 against every division in baseball. So the White Sox did not "benefit" from playing their own division since they were really .500 against every division they played. They were really a perfect .500 team.
