With most league difficulty/era factors, I've just assumed there'd always likely be a small variance between the strength of the AL and NL in any given season. Prior to free agency, the variance would probably change slowly, perhaps generationally, but now with players moving all over the place it could be prone to changing much more quicker and perhaps on a season to season basis sometimes.
I did for last year, just looking at the game logs, and interestinly enough, the game played in NL parks yields more runs, 1192, than those games played in AL parks, 1094 runs. Furthermore the AL in both cases scored more runs than their NL counterparts, when a game was played in a AL park the NL teams scored 462runs and the AL teams scored 632, and in the NL parks the AL teams scored 598 while the NL teams only scored 594. One thing is that I think it was probably wrong headed of me to suggest this in the first place "league factor", but it was still kind of fun. One problem is that not all of the teams play home and home series, so it makes it a bit harder to judge anything. Plus as I was thinking about it, these AL team are designed to play with the DH and the NL teams are not, so its hard to really draw any kind of real conclusions for interleague data. But, I thought it might be fun to look at.
