I understand that, but by the same notion, one should adjust up if it looks like there has been improvement throughout those three years and adjust down if there looks to be regression in those three years. should one not? If there is reason for the trends to continue, absolutely. so then shouldn't we ask "are there reasons for the trends to continue?" I know the answer, of course we should, and I think that's what PECOTA is all about. so it comes back to my original question, what was he using to compare Soriano and Drew? did he use numbers that show these trends, or did he pluck those that best made his points. his silence on the matter is deafening. KC, in the Sori>2006 cubs CF vs Lugo>2006 cubs ss analysis, what did you use for Sori and Lugos #s? Also, in the Drew/Pie>Sori, what did you use for Drew and Sori's numbers. Edit: Nevermind, you posted before I saw.
