(I keep posting these stats since you've never responded to them and keep harping on statements indicating players perform better at home than on the road)

How can you support that notion when basic research indicates that this is not reflective of reality? Even worse it could skew stats, as they do not necessarily balance out over the course of a season as you stated that it would:

From the Earlier Threads

I took one team (Boston) and used the three year averages (1999-2001) of each pitcher on the squad the results are presented here:
* 3 year splits missing last years stats presented

You'll also notice some pitchers (Arrojo, Burkett, Castillo, Oliver) do indeed have a big enough split between times pitching at home and times pitching on the road to skew the statistical results.
