Lineup Inpact Percentage
This offensive rating system, Lineup Impact Percentage, measures the impact of a ball player interacting with eight other marginal players [nine players including the rated player]. By measuring against eight other average players, you get more feel of a player's impact in a batting order. To be more precise, this matrix displays how many percentage points above or below the .500 mark [the mean] a player impacts in a nine player batting lineup. As a result, this matrix is bunched much closer together. LIP is more realistic as opposed to my previous measurement, purely against the league average as if only two people are competing against each other. In short, I have converted this rating into both team and lineup context.
LIP is adjusted for the rated player's home ballpark, measured against the National League, American League, and when it applies, both leagues' mean. These documented statistics are rounded off and are calculated from the Bill James Handbook 2008.
