Martin,

Have you ever given any thought to giving back some or all of the quality performance penalty, should a boxer comeback within a reasonable amount of time and pull off a significant result?

I ask in respect to Fury/Chisora... Fury proved that his prior rating was more accurate than his penalized one.

Fully revised Fury would have 690 points - and would be #2.

I will look into this ... nice idea

:TU:

We are always assuming with these types of penalties so it only seems fair to correct when the boxer proves us wrong.

If you implement this, would be curious to hear the math/logic on when/how to apply.

winner:

Hmm... A question and a comment.

How would it be handled if a boxer is not given all of his points back. Is the remainder dropped? Or is it carried over?


Also..

One unfortunate effect is that this would not help someone like Rigondeaux, should he beat his next opponent.

He is at 481 and his opponent will be ~318, which is far higher than the best opponent in the past period. You would think he'd get some of his lost points back?

I guess, the boxer should have one immediate shot only and he should have restored his pre-bout rating limited by the rating of his opponent, not more - as for Fury

Rigondeaux dropped from 680 to 481... quite severe.

Should he beat an opponent at 318 with cd=1, it seems he should probably be given some of that back?

I think if a penalized boxer is in a position where points are gained by result.. (roughly) they should be given something back.

I do not think so.

Can you tell me what the ratings would look like with this new fix and changing the poor opposition penalty minimum? Instead of 50% being the minimum, what if it were 33.3%?

I prefer the old ones.

Glazov, Huck, Hernandez, Rigandeux are too high here - for not fighting opposition for 18 months.

Realistically, Rigondeaux shouldn't be lower than #1. I just can't rationalize this. This is a good marker in my opinion.

Rigondeaux should meet opposition. The ratings go for recent achievements, not for skill or former success.

I think that last ranking set is very good. Rigondeaux has fought weak opposition since Donaire but the penalty is too large and too sudden. The problem is compounded because Agbeko looks like he got hit with a steep penalty a few months before fighting Rigondeaux as well.

For inactivity and poor opposition I think the penalties should be spread out slowly over time. The sudden hit makes the rankings look somewhat incoherent and lacking in continuity.

A boxer cannot get more than 200 points per year in the all-time-ratings.

So Mayweather would be in lead anyway, if they would retire this year both.

I just looked at Eric Molina's BoxRec page because of his matchup with Wilder, and I am confused as to how a TKO win over an extremely old Davarryl Williamson (who has very few points left) made him go from 136 to 185. That seems like way too big a jump for a nearly worthless win.

He also gained 20 fewer points for stopping Rafael Love, who had over twice as many points as Williamson did. Molina's ranking was lower when he faced Love than when he faced Williamson, so it's not as if he gained fewer points for beating Love due to some type of poor opposition factor.

Is the discrepancy here due to the slightly later stoppage of the Love fight?

BoxRec Ratings release 21 was launched.

There was a correction for missing opponent quality.

in some cases, it happened that some boxers didn't loose points, although not having faced appropriate opponent quality. This was corrected now.

I'm sure this has been mentioned, but how about a mechanism by which a fighter isn't ranked below someone they recently defeated for a certain period barring, let's say, a loss. Generally hard for me to accept someone being ranked several spots ahead of someone who recently beat them when the victorious fighter hasn't had poor results.

Current and recent examples:

-Gary Russell is 5 spots ahead of Loma even though 2 fights ago he clearly lost to him and Loma has easily won since.

-Manuel Charr is 15 spots ahead of Johann Duhaupas even though Duhaupas won their fight a few months ago and hasn't fought since while all Charr has is a win over Leapai.

-Tony Thompson was ranked behind Solis shortly after beating him even though Solis didn't fight again until their rematch, which Thompson won by stoppage. To me that was very unreasonable considering that Thompson's losses between his wins over Solis were to top opponents like Pulev and Takam, with Solis doing NOTHING while Thompson was fighting that type of opposition.

That stuff doesn't happen for no reason, though. Russell passed Loma by stopping Jhonny Gonzalez, who had stopped Abner Mares. Loma was spending that time fighting nobodies and gaining no points by the wins.

Obviously it doesn't happen for no reason, but I still don't see how that justifies the current disparities given the head to head result, which to me holds more weight than Russell's lone win since being better than Loma's wins over either of his last two opponents. Their fight wasn't too long ago and it was very clear cut, not to mention that I'd rank that win for Loma higher than Russell's win over Gonzo given that in Russell's next fight he showed himself to be superior to JG (yet he gets significantly more credit for beating Gonzalez than Loma does for beating him). I also don't see how Charr's win over Leapai justifies him being so many places ahead of a guy who beat him about two months ago.

Then you have a case like Solis-Thompson in which Solis actually did NOTHING yet managed to get ranked ahead of Thompson. In this case Thompson was wrongfully punished for fighting good opposition while Solis was rewarded for doing eff all.

The Independent World Boxing Rankings account for these types of situations much better in my opinion.
