I'm 51-58 (.468) in 1-run games, 213-152 (.584) in others. If you remove my overachieving $70M team it's even more pronounced: .413 vs. .564.
I fully expect my $70M team to regress to the mean in the second half, but it would be nice if that were combined with some progression to the mean in 1-run games for my other teams.
