Well, no, because the point of discussion was how the Twins’ record may or may not have been affected by being in a different division. So it’s only the Twins’ record that should be looked at. Of course to be completely precise if the Twins were in a different division that means the divisions would have to be realigned and one would need to take into account which teams would be in which divisions. Beyond that it would be necessary to wait until the end of the regular season. But those steps are not necessary to show that the strength of schedule has only a very small effect.
And further, the difference in the Twins’ overall record of only two wins in spite of the huge difference between the East division’s record and the Central division’s record reinforces how small the effect of strength of schedule actually is, at least as far as the Twins are concerned.
