The high scoring games in 1871 aren't too far off since back then the games had many errors and therefore you could have low ERA and high score. I admit that it does get a little high at times. I had 2 games back to back where I had to pull the starter since he was exhausted. I scored a total of over 100 runs total in those two games alone but only had 6 earned runs since the error were early in the innings. Had 35 total errors in one and I think it was like 25 in the other. Games went 9 innings each. Had 9 at bats for some players. Still nothing like the real life Niagras vs Columbias in 1869. The score was 209 - 10. Every player for Niagara scored between 20 and 25 runs including pitcher. The box score didn't paste correctly but when reading it, it's supposed to be the innings 1-9 and total for each team.
