Any chance of combining the hitting and pitching values for pitchers?

Why not adjust every facet of a hitter’s/pitcher’s game separately, because they way they derive value may or may not benefit from his park factor?

Does anyone try to do park factors that depend on handedness? For example, Safeco doesn’t hurt LHB like Ibanez but it kills RHB like Beltre. LHP do better than RHP for the same reason. Seems like this is a pretty straightforward thing that would dramatically improve their accuracy.

Everything you need to know about the park factors and how they’re calculated and why they’re calculated the way they are can be found here:

I understand park factors and why they are a good idea. But what is meant by “5 year regressed park factor”? How is the regressed part done?

The home team is only half of the park factor – the visiting team’s performance counts as well.

I only know of the six component form. I think it is a great stat, but maybe some tweaks on the sixth (fielding) factor?

I used to calculate Speed Score when the site first launched, but it was taken off for one reason or another. I think there’s a high chance it makes a return this season, maybe in its new 6 component form, though I don’t know if there’s much of a difference between the 6 component and 4 component forms.

Since they cut down on foul territory a few years ago, it plays a bit more neutral overall. Actually, in the summer I think it’s a bit hitter friendly, which is more or less evened out in the early spring and late fall. Don’t have the numbers for this, however. It’s just a guess.
