Tom,

apologies for the stupid question, but does the xERA calc formula come straight out of the Murray book? Does it have any relation to the xERA from the xera-baseball guys?

Thanks!

Yes, but Murray actually made a mistake in his book for the xERA formula. The correct formula is...

1) .575 multiplied by hits per 9 innings
Plus
2) .94 multiplied by home runs per nine innings.
Plus
3) .28 multiplied by Walks per 9 innings.
minus
4) .01 multiplied by strikeouts per 9 innings
minus
5) 2.68.

I would assume it is the same statistic used at http://www.xera-baseball.com but I can't confirm as their website makes my eyes bleed.
