2 part question:

Can you clarify the Pitcher ISO description below (highlighted in red)? It doesn't make sense to me.  I'm assuming it's reversed since it's worded the same as the Hitter ISO.  Also I'm wondering how you get pitcher ISO (or ISO allowed), if that is such a thing. Thanks, just trying to clear up some ambiguity in my mind.

Pitcher wOBA - The wOBA of the pitcher vs. opposing lineup L/R

Pitcher wOBAh - The L/R wOBA of the opposing starting lineup

Pitcher ISO - The ISO of the hitter vs. the SP L/R

Pitcher ISOh - The L/R ISO of the opposing starting lineup

Hitter wOBA - The wOBA of the hitter vs. the SP L/R

Hitter wOBAsp - The L/R wOBA of the opposing starting pitcher

Hitter ISO - The ISO of the hitter vs. the SP L/R

Hitter ISOsp - The L/R ISO of the opposing starting pitcher

The pitcher description should be different and has been updated. Thanks

For pitchers, here's more details on the columns:

ISO - the pitcher's historical ISO vs. the handedness of the opposing hitters.  This is not affected by the hitters' actual ISO, just their handedness.  So if there are 9 right-handed hitters, and the pitchers has an ISO of 0.200 vs righties, it will be 0.200.

ISOh - This is similar to ISO, but it only takes into account the hitters' ISO.  This shows the average ISO of the hitters vs. the pitcher's handedness.  The results are weighted by the projected plate appearances of the hitters so it's not exactly the average.

Does this make sense?  To review, the ISO shows what that pitcher has done, and the ISOh shows what the hitters have done.
