Its tough to get a stranglehold on the lowest of the low, while still doing well for the fighters in the spotlight. You almost need separate systems.

Surely someone who dominates a weight class has acheived less than someone who hops between divisions.

And the boxers who acheive most are generally the best.

And if the boxers who are best are best p4p...

Then why isn't Pac top?

There, is an obvious flaw in the system ^_^

Yes, the P4P chart is very flawed. It should be taken down, imo, as it detracts from the divisional charts (which are very good).

It should be renamed to division dominance, because that's what it is.

Thats one way of measuring P4P though isn't it? Perhaps the only objective method
Not when some divisions are weaker than others.

I was wondering if there might be scope for improvements at the other end of the scale i.e. down amongst the tomatos.

Some thread showed the Zelenoff vs Hartley clip and so I went scanning for the ranks of these fighters. Both were quoted as unranked, which is understandable for Zelenoff, but questionable for Hartley. I mean, the guy has had 15 or so fights now and so that's quite a data set to rank him with.

Anyhow, I went to the ratings link and selected all the U.S Welters. Sure enough, all the welters are there, with their points total. Many have the same points total, and yet seem to be sorted in a reasonable order, so I guess there is an unpublished number helping this sorting.

Anyhow, amongst the curiosities that I saw.

Carrine Hammlet http://www.boxrec.com/list_bouts.php?hu ... &cat=boxer has a draw and a SD loss, so I'm surprised he landed on 0 points

William Deboe Thomas http://www.boxrec.com/list_bouts.php?hu ... &cat=boxer who has only fought twice, and lost both, ended up a) with a rank and b) with 3 pts. Probably the MD is valued higher than the SD, whereby, the SD was actually better becuase Hammlet won on one judges card, whereas Thomas did not.

Josh Durden http://www.boxrec.com/list_bouts.php?hu ... &cat=boxer is also on 0 pts, despite a run of 5 wins and 0 losses. Admittedly, he has fought the worst of the worst, but nevertheless, 5 wins and 4kos against this opposition would mean to me, that he is probably a tick better than the other 0pt fighters.

Rafael Estradahttp://www.boxrec.com/list_bouts.php?hu ... &cat=boxer same goes for Rafael who has at least some wins (including a win against someone who won a fight) and a draw against Sook what's his name, who is obviously not complete dirt either.

Getting back to the original two fighters. Intuitively I’d say, that someone who beats someone , even if it is a debuting fighter, is generally better than them. I’d rank Hartley above Zelenoff. Naturally you shouldn’t be able to rocketing up the ladder by KOing a bunch of 0-0-0 or 0-1-0 fighters, but I’d still give you at least 1 pt for the win. And I’d probably rank someone higher, who has beaten 5 such debuting fighters as someone who has beaten just one.

Probably all this is reflected in a mystery hidden number somehow. Still I think some improvements are possible.

Any comments computerrank? Surely improving the bottom ends up improving the top at some point.

Only full points are presented in the ratings. But the ranking (look at the rank independent of rated or not) depends on the part points too.

All boxers below 1 point are 'not rated'.

Hartley vs Zelenoff

Hartley 0.010
Zelenoff 0.001

But both below 1 and so unrated.

Hi computerrank,

Thanks for the behind the scenes info. A lot more makes sense, however I am left with the following question marks.

Josh Durden 5-0 (against unknown scrubs) and Charlie Zelenoff 0-1 (against ultimate known scrub Andrew Hartley) both have 0.001 Pts?

Hartley who has only beat two 0-0-0 fighters and lost a lot more, is ranked above Durden.

That seems a little unfair on Josh. I mean, Hartley has proved that he very beatable, yet Charlie couldn't do it. That has to rank Chrlie lower than Durdan who has at least won five times against opponents, who have not yet become so low as Andrew Hartley.

(@Andrew, if your reading, all respect to you, you're just an example here, not having a go at you).

I dunno how I'd do it, but I'd probably start by doing a first pass of the database, looking for absolute zeros. Fighters who in their career never won or drew a match. These fighters can barely contribute to another figthers record. Then you do a second normal sequential pass.

When you fight such a marked fighter, you get say 1pt for beating the first one,0,5pts for beating the second one, 0,25 pts for beating the third. So you can max out at 2pts, for beating 20 0-0-0 fighters in a row.

More later. Important it to cheat and do two passes of the db.

cheers

Hi computerrank,

continuing on with my bottom trawling. I looked at some US heavies.

US Rank 311 Freddie Miller http://www.boxrec.com/list_bouts.php?hu ... &cat=boxer got his first win by UD against an 0-0-0 opponent.

However, he lands ahead of

US Rank 315 Brandon Mayweather http://www.boxrec.com/list_bouts.php?hu ... &cat=boxer who got his first win via KO1 against a different 0-0-0 fighter. I would've assumed that Mayweather's win would've been worth more as it is more conclusive.

And I'm surprised that both land ahead of

US Rank 319 Newbie Jackie Saye http://www.boxrec.com/list_bouts.php?hu ... &cat=boxer who has three KO wins against lacklustre opposition. One of the three wins is against a 0-0-0 guy, so effectively Saye has achieved what Mayweather and Miller have achieved and then some more, yet he is ranked behind them.

Any clues on that.

thanks

I am worried about the Thailand results...

Only the high profile fights get set to unsanctioned (like Wonjongkam v Miranda), while many of the mid-level fights do not. I was informed by Scott Mallon that all Thailand bouts should be to unsanctioned.

However, this would have quite an impact on some fighters' ratings.. like Pongsaklek.

I think this should be reconsidered...

As I can see, nearly all bouts in Thailand and Philippines are unverified - this is not the same as unsanctioned.

Only unsanctioned bouts are accounted with 50% only.
