division_factor

[JussiNiemonen]

Would you kindly be able explain how exactly the "division_factor" works?

And could you better explain this: "For lower weight divisions the points are converted with the cube of Heavyweight upper weight reference in relation to the upper weight reference of the Boxer's weight division." with numerical examples and/or in layman's terms?

Or could you explain using any current boxers as an example how the points/ratings are effected for each when a boxer rated at say Lightweight meets a boxer rated at Featherweight in a bout contested at Super Feather, and also how their points/ratings gained/lost by the result of that bout are effected when they later move back to the weight divisions they came from?

The current BoxRec rating points of a boxer are independent of the weight division he is assigned to. They only depend on the official results during his career and the ratings of his opponents.

But if you compare the resulting ratings points of the best Heavyweights with the rating points of the best Minimumweights you will find that the Heavyweights are ranked significantly better.

That doesn't disturb the ranks of the boxers within a distinct division. But in a pound-for-pound list the Minimumweights would rank worse with this disadvantage.

In order to compensate for this disadvantage the rating points in different divisions are multiplied with factors depending on the weight ratio of the weight divisions - or on the power of such a ratio.

Let's assume Heavyweight boxer A has 100 points, and Minimumweight boxer B has 50 points. Then Minimumweight points are multiplied with the ratio of the upper weight division values.

The upper weight limits a used, because they represent the common weight for a boxer in this weight division. This is 105 pound for Minimumweight. Heavyweight has no upper weight limit, but 240 pound is used as common weight in this weight division.

Back to the example: The used factor is 240 pound / 105 pound = 2.29. That gives boxer B 50 * 2.29 = 114.5 comparable points in a pound-for-pound list.

You may instead use the cube = 3rd power of this ratio, which is 2.29 * 2.29 * 2.29 = 12. This would give a comparable rating of 600 points for boxer B.
