    Your making a big stink about one guy

    so just having Manny under Floyd is enough to call a rating system totally flawed and useless

    look at the other weights they are dead on or the number 1 and 2 are interchangeable

    better than the WBA's ranks

    Lucien Bute as no. 1 at SMW is also a bit odd, surely? Fans are often split but he is pretty untested compared with, say, the Super Six contestants. Is there just too much weighting on win ration, or do they really think that he should be ranked higher than Froch, Ward et al?

    its really up to opinion Bute Ward Kessler and Froch all can lay claim to number 1

    To me Bute an Ward are interchangeable and so are Manny and Floyd

    Current ("Active") rating


    1. Every boxer gets a first rating of 0 before his first bout.
    2. After every bout, the ratings of the two boxers involved are changed depending on the bout's official result (KO, TKO, RTD, UD, PTS, NWS, MD, SD, DQ, TD, DRAW).
    3. The value of a result varies between v=1 and v=0.
    4. The clear decision factor varies between cd=1 and cd=0.
    5. The winner cannot lose points for KO, TKO, RTD, DQ, TD and decisions on points with cd=1
    6. KO, TKO, RTD are rewarded with full value v=1, cd=1.
    7. NWS is rewarded with full value v=1 for 12 rounds boxed and more and a lower value related to the number of rounds boxed. Clear decision factor cd=1.
    8. UD, PTS are rewarded with full value v=1 for 12 rounds boxed and more and a lower value related to the number of rounds boxed, clear decision factor cd=1. This is valid, if the score cards are not available.
    9. DRAW is rewarded with full value v=1 for 12 rounds boxed and more and a lower value related to the number of rounds boxed. Clear decision factor cd=0.
    10. MD, SD, DQ, TD are rewarded with full value v=1 for 12 rounds boxed and more and a lower value related to the number of rounds boxed. Clear decision factor cd=0.5. This is valid, if the score cards are not available.
    11. If the score cards are available, the value rewarded is in direct proportion to the rounds boxed, with full value v=1 for 12 rounds boxed and more. The clear decision factor is in proportion to rounds boxed and the mean score difference per judge. cd=1 for a mean score difference per judge of 50% of the rounds boxed.
    12. All bouts are regarded to have the same weight independent of titles.
    13. The winner gets a certain part of the opponent's points and a certain part of the rating difference to the opponent's rating.
    14. For a DRAW the rating of the higher rated boxer is reduced by some part of the point difference; the rating of the lower rated boxer is enhanced by the same amount of points.
    15. The full relative point reward is 33%. It is in direct proportion to the pre-bout rating of the defeated opponent.
    16. The winner can get up to 25 additional points per opponent's launch state rank
    17. The maximum launch state rank regarded is 15 - and so the maximum number of additional points is 375
    18. The maximum additional points are reduced to the opponent's rating but to not less than 6 * (launch state rank +1)
    19. This value is multiplied by the maximum additional points reduced by the own rating, and it is set in direct proportion to the rounds boxed and the clearness of the decision
    20. This value is multiplied by the quotient of the maximum of the opponent rating and 6 * (launch state rank +1) on one side and the sum of the maxima of the opponent rating and 6 * (launch state rank +1) and the maxima of the own rating and 6 * (launch state rank +1
    21. Launch states are:
      1. 0 = no recent win
      2. 1 = 1 recent win, 2 = 2 recent wins, 3 = 3 recent wins
      3. 4 = recent win over opponent with state 3, 5 = 2 recent wins over opponent with state 3, 6 = 3 recent wins over opponent with state 3
      4. 7 = recent win over opponent with state 6, 8 = 2 recent wins over opponent with state 6, 9 = 3 recent wins over opponent with state 6
      5. 10 = recent win over opponent with state 9, 8 = 2 recent wins over opponent with state 9, 9 = 3 recent wins over opponent with state 9
      6. 13 = recent win over opponent with state 12, 14 = 2 recent wins over opponent with state 12, 15 = 3 recent wins over opponent with state 12
    22. The ratings are decreased for moving up to higher weight divisions by the square of the reciprocal ratio of the weights limits of the divisions--and they are increased by the same factor for moving down the divisions.
    23. The rating of a boxer is reduced by 0% to 50%, if he didn't box an opponent with a rating of at least 50% to 0% of his own rating points within 18 months.
    24. The rating of a boxer is reduced by 50% for every time period of inactivity of 18 months.
    25. The pre-bout rating of a boxer successfully returning from inactivity is set to the lower value of his own rating before inactivity and the higher value of his own rating after inactivity and the pre-bout rating of his opponent.
    26. The pre-bout rating of a successfully debuting boxer is set to 25% of his opponents pre-bout rating.

    Formula
    If a boxer with a rating of r_a before the fight defeats a boxer b with a rating of r_b before the fight with result of value v and clear decision factor cd, the new ratings r_a_new and r_b_new after a fight are, earn_f is 33.3%:

    • earn = earn_f * v * (r_b*cd + (r_b-r_a)/(1+2*cd));
    • r_a_new = r_a + earn
    • r_b_new = r_b - earn
    Additional points (no additional loss points accounted):

    • opponent in launch state n: v * cd * (25*n - r_a) * min( (max(6*(n+1),r_b), 25*n) / 25*n * max(r_a,6*(n+1)) / (max(r_a,6*(n+1) + max(r_b,6*(n+1))
    (http://boxrec.com/media/index.php/BoxRec_Ratings_Description)

    In other words, it's an objective rating determined by a formula. So there you go, now you know why he's ranked that high. Let us know when you find a better formula so you can correct this "laughable" ranking.
