Would you guys agree that in general a MLB team should be "ten percent better" with home field advantage? By ten percent better I mean that if a given pitcher has an ERA of 3.00, with home field this can be reduced to 2.70. Similarly, if a given team's offense were lumped into one sum-say 50 for example, this could be increased to 55. I realize there are stats already provided for "home/away" but I'm looking to come up with a general rule. Let me know your opinions and good luck!
