What's the Average?

So recently I've been expanding my statistic Pitching Performance Value. So whats the average value of a start. The average amount of innings pitched from a starter is 6.0 so that means they recorded 18 outs. Also the average ERA in the major leagues is 3.94. That means over 9 innings a pitcher would give up 3.94 earned runs. That turns out to be 2.63 earned runs over 6 innings. Additionally the average whip for a pitcher is 1.32, so tha means over 6 innings pitched 7.92 base runners will reach base. Finally the average OPS of a hitter is .720. So do a quick calculation the average Pitching Performance Value is 62.22. Anything above 62.22 PPV from a pitcher's start would be above average. If a pitcher consistently gets PPV's above 62.22 he is considerably better than the average pitcher.

Coming soon: A way to adjust PPV for the ballpark the pitcher is in.
