A message from owners of Boxrec

just so you know John is the overall owner of boxrec, Martin does editing to the website and maths calculations and Marina does most of the Admin work which is second in charge (and wife to john).

This Letter is from Marina:

"Martin and John updated the rating program last night. 
From Martin: 
"The change is about the additional points.
Based on the basic symmetric rating formula the sum of the ratings of both opponents are constant before and after the bout.

Boxers lose points caused by inactivity and missing opponent quality

Every day boxers retire and take their points out of the system. So it is essential to feed additional points into the system.

The previous additional points formula was very complex (more than 40 categories, a ladder system, boxers climbed up and down) and so in-transparent and more it showed some loop holes that allowed too much additional points by defeating boxers with good formal records, or only historical achievements.

So I simplified the additional points formula (only 3 categories) and made it more dependent on the ratings ratios as in the basic formula.

In short - I simplified the formula and cut down the loop holes. The ratings now stronger depends on the basic rating formula only."

The prediction rate will rise a lot through this.

Martin also changed the division allocation, but I don't think that will work for most boxers so I'd like to revert that back to what we had before last night.

I've been dealing with complaints all day, I do hope the same does not go for you

- Marina"
