i think teh Boxrec computer system puts huge emphasis on beating champions and since Cotto has generally won vacant belts he gte penalised, same with pac, he hasn't actually beaten many actual title holders since he is obviously more interested in fighting great fighter rather than for meaningless belts.
I only use Boxrec as a historial database.Comment

Only till the end of like the 8th Cotto start dancing, I didnt really see why,
but he seemed to be in control the whole fight against an old veteren. Only 36, and Cotto is only 28 years old. People have trouble in fights, even against "supposely old guys".
I seen it meny times.
Looks like Cotto is way above in skill level, and he looks like a young prospect in there.Comment

Here is the explanation..... may as well be written in Chinese.
All these ratings evaluate every day all bouts in the database in chronological sequence. A higher rated boxer should be expected to defeat a lower rated boxer with increasing probability by increasing rating difference.
Current ("Active") rating
Every boxer gets a first rating of 0 before his first bout.
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).
The value of a result varies between v=1 and v=0.
The clear decision factor varies between cd=1 and cd=0.
The winner cannot lose points for KO, TKO, RTD, DQ, TD and decisions on points with cd=1
KO, TKO, RTD are rewarded with full value v=1, cd=1.
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.
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.
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.
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.
If the score cards are available, the value rewarded is in relation 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 mean score difference divided by a sixth of rounds boxed greater or equal 1.
All bouts are regarded to have the same weight independent of titles.
The winner gets a certain part of the opponent's points and a certain part of the rating difference to the opponent's rating.
The winner gets at maximum 50 additional points, if his opponent's rating is higher than or equal to a quarter of his own rating. The 50 additional points are reduced by half the rating difference between the winner and the loser. The maximum of 50 points is only awarded, if the defeated opponent has 5 wins at minimum. In other cases the amount is reduced in relation to the number of wins.
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.
The full relative point reward is 33%. It is in relation to the pre-bout rating of the defeated opponent.
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.
The ratings are equalized between divisions in relation to average points of the boxers ranked #8, #9, #10, #11 and #12 in a division.
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.
The rating of a boxer is reduced by 50% for every time period of inactivity of 18 months.
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 new_a and new_b after a fight are, earn_f is 33.3%:
earn= earn_f * v * ($r_b*cd + (r_b-r_a)/(1+2*cd));
new_a= r_a + earn;
new_b= r_b - earn;
Examples
Boxer a KO boxer b, a has 1000 points, b has 500 points. v=1, cd=1
earn= 0.33 * 1 * (500*1 + (500-1000)/(1+2*1)) = 111
r_a_new = 1000 + 111 = 1111
r_b_new = 500 - 111 = 389
Boxer a UD 6 boxer b, scores 59:55 58:56 58:56, a has 1000 points, b has 500 points.
A 6 rounder is rewarded with value 6/12, v=0.5
UD is rewarded with cd=1 at maximum
mean score difference per judge is (4+2+2)/3 = 2.667, which is rewarded in relation to half the rounds boxed with cd= 2.667/3 = 0.89 at maximum
so cd=0.89
earn= 0.33 * 0.5 * (500*0.89 + (500-1000)/(1+2*0.89)) = 44
r_a_new = 1000 + 44 = 1044
r_b_new = 500 - 44 = 456
Boxer a SD 4 boxer b, scores 39:37 39:37 37:39, a has 1000 points, b has 500 points
A 4 rounder is rewarded with 4/12, v=0.333
SD is rewarded with cd=0.5 at maximum
mean score difference per judge is (2+2-2)/3 = 0.667, which is rewarded in relation to half the rounds boxed 0.667/2 at maximum\
so cd=0.333
earn= 0.33 * 0.33 * (500*0.33 + (500-1000)/(1+2*0.33)) = -15
r_a_new = 1000 - 15 = 985
r_b_new = 500 + 15 = 515Comment

Who cares? P4P lists are always open for interpretation. I do agree he should be somewhere in the top 15 tho.Comment
Strum sucks. I guess Paul Williams is up there because he's fought at WW JMW and MW, which is p4p style even though he fought a bum at JMW.
