Yesterday I posted some tidbits on the Cardinals and their Pythagorean record. Finishing up that post was partially inspired by a conversation in the comments at VEB. One of the comments was along the lines of, “what’s the point of the Pythagorean record?” In an attempt to add some information to the discussion, I wanted to see how much (if at all) better Pythagorean record was at predicting next years record than actual record. The following two charts are the results for the Cardinals.
So while neither is great at predicting next year’s record, Pythagorean record does have a higher correlation.
