It is the next version of a rank of ranks. Kenneth Massey has made a remarkable thing - has collected about hundred ranking systems of College Football teams. And having assumed, that as behind everyone ranking authors stand and all of them are equal and are the experts as though armed with mathematics. And time so that is naturally simple to calculate certain average ranking, for example, by summing ranks of teams. As has truly noticed by Kenneth Massey models of an estimation of validity of ranks much. Probably as much how many models of ranks. More or less the general structure probably is fair ESTIMATION of the MISTAKE = IMPORTANCE of MISTAKE * SIZE of MISTAKE Here: IMPORTANCE of MISTAKE = SIZE of MISTAKE = ESTIMATION of DEFEATED RANK - ESTIMATION of WINNER'S RANK It results in beautiful expression: ESTIMATION of MISTAKE = In the previous version the elementary estimation of the RANK of participants was used 1. RANK ESTIMATION = N - RANK However it only one of possible elementary arithmetic expressions and no more that. To look as influence various estimation models of the RANK, I used some more expressions 2. RANK ESTIMATION = N / RANK - gives more "attention" to the top rank 3. RANK ESTIMATION = (N-RANK) / RANK - product of the two first estimations
