Solving for the sample size issue, it turns out that the current model largely balances out in the World Series.  Since they went to deciding the DH rule based on the site of each game in 1986, meaning where there have been games in each World Series played with and without a DH, there have been 70 games played with a DH and 72 games played without a DH.

 

In the 70 games played with a DH, the AL teams are hitting .259 (597-2,301), while the NL teams are hitting .239 (575-2,401).

 

In the 72 games played without a DH, the AL teams are hitting .242 (607-2,401), while the NL teams are hitting .252 (603-2,392).

 

Thus, the NL is hitting 13 points lower with the DH than without.  The AL is hitting 17 points lower without the DH than with.
