I think it's fair for us to assume that you did too.

Do you consider this a valid answer: "Originally Posted by SAump
ERA = Earned Runs Allowed / Innings Pitched * 9 Innings

For more info, check out http://en.wikipedia.org/wiki/Earned_run_average"

This did NOT answer what I asked. The problem wasn't my not knowing fractions. I know fractions. But until I was shown the section of 10.22 that mentions fractions, I was unaware of using fractions in determining ERA, though I did use that system, because it made sense. But I couldn't find anything in print to validate it. I must take blame for not reading 10.22 more carefully earlier, because I hadn't noticed the mention of fractions.

Complicated by age level difference?

Is this ERA stat only used to compare 9-inning games? Other leagues playing within appropriate age levels only allow 5, 6 or 7 inning ballgames. For example, a young child with a 6.00 ERA over 9-innings would lower his ERA to a 4.00 ERA over 6-innings. Shouldn't we adjust the ERA formula to match the number of innings at each particular age level?
