Apologies if my question has already been answered - I had a search but it's like finding a needle in a haystack.

My question: Usyk entered the heavyweight division at 563.1 points - how is this starting value calculated?

This puts Usyk at #3 in the Heavyweight rankings already, despite having only one fight at the weight against an absolute nobody (Witherspoon). Most people's top 3 involve Fury, Wilder and Joshua so it's a surprise to see newcomer Usyk fly straight in at number 3.

Obviously, it's plausible for Usyk to be ranked so high because he's an absolute master but his results in the division don't yet justify such placement.

So, how is a boxer's starting value calculated when he switches division? Cheers!

Chris Eubank Jr also just switched division - he flew back into Middleweight with a whopping 708.1 points (he was 613.0 at supermiddle). So switching division has boosted his rating by almost 100 points.

That makes him #2 at Middleweight (second only to Golovkin) and #12 P4P.

Maybe Middleweight is a weak division atm, which helps Eubank Jr place at #2 but in no reality is Chris Eubank Jr the 12th best fighter on the planet above guys like WBSS winners Naoye Inoue and Josh Taylor.. Feels wrong.

The computer can only see the result KO 2 over Matt Korobov, which is an impressive result when the result is all you can see.

Eubank Jr was rated 708.1 before the Korobov fight even began. Beating Korobov raised his score less than 1 point to 709.9, so the computer was not so impressed with the win (Korobov is rated just 79.9).

So it's nothing to do with Korobov. Eubank just switched division and was gifted a ranking of 708.1 at Middleweight after returning to the division after three years. I want to know how that initial value is calculated when a fighter switches division.

It can't be right Eubank comes straight into a new division at #2. Switching division sent Eubank's rating through the roof to #12 P4P. Feels wrong.

I wouldn't concern myself too much with the rankings the computer generates.

When a boxer is assigned to a new weight division, his points are converted with the next daily ratings program run. At a higher weight division the points are decreased, at a lower weight division the points are increased.

The conversion goes with the ratio of the corresponding weight limits raised to 3rd power.

e.g. for a conversion from Cruiserweight (200 pound) to Heavyweight (240 pound assumed) 1 point at Cruiserweight is equivalent to (200/240) * (200/240) * (200/240) = 0.833 * 0833 * 0.833 = 0.579 points at Heavyweight.

I see, thanks for the explanation. I can see the logic why a fighter moving down a division would be given an advantage, ratings wise. Although I'm not convinced it works for a fighter returning to his natural weight, as Chris Jr is. With this logic a fighter could move up a division, take an easy fight, then move back down to their natural division and receive a massive ratings boost.

I'm also struggling to comprehend how Eubank Jr moved from 56.05 to 116.4 after losing to Billy Joe. Billy Joe moved down from 260.7 to 202.6 after beating Eubank Jr. Something feels amiss.

The divisional point shifts are reciprocal... If a boxer moves up in weight and beats a scrub, the gain will be as minimal as if he had done it and stayed in the same division the entire time.

Eubank/Sanders was closer than the point difference suggested... so the totals moved toward the midpoint.

I think I've figured it out now - it's a Split Decision thing. Kid Galahad gained ~100 points after losing to Warrington, Luke Campbell gained points after losing to Linares - all split decisions.

It's still debatable though whether a guy's rating should collapse after getting the win..

Seems fair to me.. but I'm just one man. When the decision is so close to a draw, it may as well be treated like one in a points-based system.

Eubank has always fought and beaten boxers with decent boxrec ratings.. Only explanation.

Why is Joshua above Fury on the active lb for lb list but Fury is above Joshua on the all time lb for lb list?

[computerrank]

Why is Joshua above Fury on the active lb for lb list but Fury is above Joshua on the all time lb for lb list?

The current ratings depend on the recent results.
The all time ratings depend on points accumulated during the whole career.

Surely AJ has accumulated more points from opponents than Fury.

Hi guys, what do we have here, is it explained anywhere? Some sort of test-harness for unreleased changes maybe? Can i contribute somehow?

Hi there.

Here is an odd ranking.
https://boxrec.com/en/proboxer/334639

A 70 years old boxer makes comeback after 36 years. He beats a guy in supermiddle/light heavyweight. His opponent has never won and is 0-6 and as never fought above 140 lbs. Now the 70 year old is ranked 641/1863. So about the best third of the superwelter division.

I think there is an issue with points, that are almost the same after such a long layoff.

Damn, that IS strange. The fight's on YouTube BTW -

Personally, I think after missing X years, you go back to a debuting fighter (or awful damn close to it) -- also treated like a debuting fighter should there be a rockstar-level unexpected performance.. I don't really know what X is... 8?

[computerrank]

Very odd, indeed
In the current release, a boxer cannot lose points by inactivity or missing opponent quality below his 10 percent career top rating - even after 30 years.
This will be changed.

One thing I noticed that weirds me out.. is the fact that Golovkin gained 30 points by beating Steve Rolls.

Pre-fight, Golovkin had nearly 50x the amount of points as Rolls...

Rule 7ff

- when defeating an opponent within the top 15 percent of all active boxers, who already defeated an opponent within the top 15 percent of all active boxers (top 15 percent limit 2019: men = 4.89 points, women = 1.87 points)
-- 8 points at least
-- as much points as the defeated opponent had before the bout
-- 40 points at most

I know it meets the specifications, it just seems crazy from the outside.

Is there a date when the new version of the rankings will be released?
