The name Log5 is due to Bill James [1] but the method of using odds ratios in this way dates back much farther. This is in effect a logistic rating model and is therefore equivalent to the Bradley–Terry model used for paired comparisons , the Elo rating system used in chess and the Rasch model used in the analysis of categorical data.
Building upon the run batted in (RBI) statistic, the game-winning RBI was defined in MLB rules as "the RBI that gives a club the lead it never relinquishes."

In the most basic runs created formula: = (+) + where H is hits, BB is base on balls, TB is total bases and AB is at-bats.. This can also be expressed as = = where OBP is on-base percentage, SLG is slugging average, AB is at-bats and TB is total bases, however OBP includes the hit-by-pitch while the previous RC formula does not.

A team with a lower winning percentage may lead (in terms of games behind) a team with a higher winning percentage. [4] For example, Team A at 6–4 would lead Team B at 2–1 by a half-game when calculating games behind. However, Team B has the better winning percentage at .667, compared to .600 for Team A.
