Chris Norrad is my brother! :D

Can someone please explain why Jimmy Bivins is #4 in the All Time Heavyweight Ratings? This is just plain wrong.

how much work would it be to provide the user with an option to view the database at a certain point in time?

if I wanted to know what the database - had it existed at that point in time - looked at on say 1st Jan 1955... as opposed to the All-Time ratings. I guess this would mean 'running' the bout calculation from year dot and then stopping it once all bouts prior to that date had occured...

also, any chance of being able to produce a boxers points progression through his career as one line graph?

I have read his record. There is nothing in that record that qualifies him to be rated #4 Heavy.

What he's trying to tell you is that he was set to the wrong division for all-time calculations. He is now at Light Heavy.

- ratings on Jan 1 for every year -> would mean to store 2 additional values (division and points) for every boxer and every year - this would be millions of additional values to be updated and stored every day -> overload

- one line graph for rating points -> problem: division moves within career

The problem is, that the points decrease / increase technically in case of weight division step-up / step-down.

But it'll only be after they've had a fight that division, right?

In which case I think it's fine. I'd really like to see it, especially for the boxers with a lot of fights.

Would that graph really add any utility, especially considering rating inflation (or even deflation), division changes, etc?

I think an annual Top 50 in each division would be more useful.

You have to run through all the bouts - just as the daily rating program does.

It needs minutes and binds a lot of computing ressources.

So such requests are not acceptable for a click call by every user - sorry.

A corrected release of Boxrec Ratings was just launched.

The requirements for getting additional points were a bit increased for new and low rated boxers below 50 points.

Along the bout history some higher rated boxers are effected too.

I noticed this when looking at Margarito's record and thinking, wow, I really thought he'd been coming into fights with higher ratings than that... Then I see the ratings through Pacquaio's history are a lot lower than I remember them, too. Sorry if I'm missing some place where it was explained, but did the new change mostly affect the ratings of a certain group of fighters? And did it mostly cause ratings to go down? What is it that changed, if it can be put simply?
