BoxRec Top 20 P4P for ****s & giggles.

[The Gambler1981]

Boxrec is based on mathematics formula that nobody really know where it comes from.

This is a great site to get fights history and results, but it means nothing for the ranking.

I know that, although I think they have alright division rankings but P4P adds a whole other layer that makes it very hard to do by formula.

I find them interesting to look at but don't put any really stock in it

Do you know what is the formula they are using ? I'm an actuary so it has always intrigued me...

The more popular and the higher weight, the more points you get, there is no formula. Guys like Estrada and Roman are ranked liked 60 P4P

21 . This value is multiplied by the quotient of the maximum of the opponent rating and 18 on one side and the sum of the maxima of the opponent rating and 18 and the maxima of the own rating and 18

23. 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.

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) * max(6*(n+1),min(r_b,25*n)) / (25*n) * max(r_a,18) / (max(r_a,18) + max(r_b,18))

I think there is a link to it on their website, I like when you turn on the chart on the fighter pages so you can see how each fight changes the ratings.

It is a formula~ it certainly is not perfect though especially in a P4P sense, like I said B-Hop lost points and his top ranking at 175 last night based off 1 bad scorecard even though he easily won.

Boxing ranking is qualitative and math formulas don't do qualitative which is why anyone with eyes notices issues right away.
