clarification about ratings

[lesov]

I am making an online boxing game and would like to use the system of ratings you have here. I will give you full credit for it of course.

First is it ok with you?

Second can you provide some clarifications so I get it right?

- Can you explain exactly how the draw is handled. The description is not clear to me.
- Can you also explain exactly what the line below means.
"The ratings are equalized between divisions in relation to average points of the boxers ranked #9, #10 and #11 in a division. "
- Also for new boxers, both debuting (both having 0 as current rating) the formula would not work. So what do you do in this case?

Thanks,
Pavlik

Wether you might use the formula, ask JohnShep by PM.

Draw:

- The boxer with better pre-bout rating loses a third of the rating difference to the pre-bout rating of his opponent - his opponent wins a third.

- This is only true for a 12 round bout - the adaption is lower in relation to the rounds boxed.

Division rating adaption to level of #9,#10 and #11:

- You get a measure for the excellence of the top boxers in the division. If #1 in the divison has 200% of this average rating, he is excellent. If he has 200% this is about at the entry level for the top 25 p4p.

- This adaption does not change the relations inside a division, but allows to have a p4p rating.

Both opponents are debuting:

- Both pre-bout ratings are 0 - so where is the problem?

thanks for reply , that makes sense.

the problem with both opponents having 0 as ratings and then fighting each other is that if formula is used they both will end up with 0 rating again no matter what the result is.

#The winner gets a certain part of the opponent's points and additionaly a certain part of the rating difference to the opponent's rating. The winner gets at maximum 25 additional points, if his opponent's rating is higher than a quarter of his own rating. The 25 additional points are reduced by half the rating difference between the winner and the loser.

... so in case of both being debutants, the winner gets 25 additional points for a clear decision and a 12 round bout. He gets less for a less clear decision and less rounds boxed.

I guess i was confused because of this " if his opponent's rating is higher than a quarter of his own rating.", which is not true if both ratings are 0. So the formula was not working because 0/4 is not < 0.
Thank you for helping me understand.
