Ratings	Iterative Strength Ratings Boyd Nation's Iterative Strength Rating Conference summaries Iterated Strength of Victory This is the ISR with a Margin Of Victory component. Conference summaries Directed Games Graph These are not "ratings" per se, but two different functions of win chains (A beat B beat C...) based upon the shortest such chains between two teams. Second order winning percentage (based upon number of Bs, Cs, etc. for each A) Weighted by number of paths and length of path

Often people who are not familiar with the nature and limitations of statistical methods tend to expect too much of the rating system. Ratings provide merely a comparison of performances, no more and no less. The measurement of the performance of an individual is always made relative to the performance of his competitors and both the performance of the player and of his opponents are subject to much the same random fluctuations. The measurement of the rating of an individual might well be compared with the measurement of the position of a cork bobbing up and down on the surface of agitated water with a yard stick tied to a rope and which is swaying in the wind.
