    Note that the team rankings are based on tournament-strength.

    SHP-
    I read these earlier and was wondering the exact formula used -
    i.e.-strength of schedule + win margin-(major worth more than dec )-and over all record ??
    I am not a big fan of rankings but these might be a better way as you take the human bias out of the equation .
    If you'd PM me the exact formula or e-mail me I'd appreciate it very much .
    THANKS.

    I quote from the article:

    "The basic idea is an iterative one. Begin with all wrestlers set to an even rating -- 100 in this case. Then, for each match wrestled, give each wrestler the value of their opponent's rating plus or minus a factor for winning or losing the match -- 30 by decision, 40 by major/tech-four, 50 by tech-five, 60 by fall. Total all of a wrestler's results, divide by the number of matches wrestled, and that's the end of a cycle. Then use those numbers as the start of the next cycle until you get the same results for each wrestler for two consecutive cycles."

    Excellent-
    All wrestlers begin evenly without the preconceived notion that Wrestler A is better than Wrestler B because of past events .THANKS.

    I tried the formula and it works -yet isn't this more a reflection of the wrestler's value to his team as to where he should be ranked ??
