If a batter has 1 PA, 1 AB and hits a HR during that AB, what should the RPA be?

In this case, the displayed RPA is 2? Is this correct?

This was covered in another post (http://iscore.freeforums.org/runs-per-at-bat-t356.html" onclick="window.open(this.href);return false)

It is (runs + RBIs)/Plate appearances

Your very basic scenario got me to thinking about this more. It doesn't seem like a hitter's run production average with a single at bat and a solo home run should provide a run production average of 2. As you probably expected, it should be 1.

I did a little hunting around trying to find some more information on this, but it is pretty scant. I did find an article in the NY Times, though, that states RPA is calculated as:

(runs + rbi - hr )/plate appearances

This prevents home runs from being counted twice as part of this statistic, as you are seeing happen in your scenario.

This looks like a job for "the Monkey Boys" (tm)

That appears to be correct... we need to subtract out home runs and are not currently doing that. We will fix it for version 1.70.

Thank you.
