First, I should say that this was an investigation of a topic that came out of that debate. It was not meant to settle the debate. During the debate, we argued about whether "better" teams have an advantage in the playoffs. It is a topic we have touched on often, and I think we have waffled on it, most recently during the postseason. I realized afterwards that I don't have any idea what is true regarding that question, or to what extent it is true. Let me be specific about what I showed above: this shows that the number of wins a team has in the regular season is a poor predictor of their chances of winning a championship. I'll be honest - I was dumbstruck by how low this factor is. It might be that there are other predictors, and one of those predictors might have something to do with strength of schedule or divisional strength or starting pitching or whatever. But to conclude that any of them are important, one must define them. Maybe we should judge teams by something like wins times a factor for strength of schedule. Great. Then do so, and show it predicts success in the postseason. But otherwise, I don't see any difference in saying that a team is better because they had more regular season wins than saying a team was better because they had a higher batting average. Both are nice, but both are ultimately unimportant. I'll go a step further - and I think this might be important. This suggests that the best strategy for an organization to win a championship is NOT to push all their chips to the middle of the table and become really, really good (as judged by wins) for a few years. It is to extend their window of opportunity as long as they possibly can and make the postseason as many times as they can. For the record - I think the Rays are following this strategy. I think the Twins do too, though I think it's a side effect of a core belief in giving opportunities to minor leaguers.
