Question

Your pool game is a joke your rating system and points do not make sense.are there any white people doing it.

Answer 1

Yahoo! Pool scoring is kind if mysterious, but not completely impossible to understand. You start out with 1200 points and a provisional status. After playing 20 games you are no longer provisional and your actual score will show up in the right-hand column beside your name.

Now for the good part. Scoring is based on the rating of your opponent. You are encouraged to play people with a higher score than you possess,because playing someone lower results in a greater loss of points if you lose the game.A 1200 rated player verses another 1200 player will result in about 15 points changing hands. If a 1200 player beats a 1400 player, he will receive around 20 points. A person rated high, say 1800 or more, will not gain many points for beating someone rated low.

I've built up to 3500 points before, ( by boosting ) and I did not gain a single point for winning against lower ratings. Each loss cost me 32 points.

I hope this helps.

Answer 2

I'm not quite sure what part of billiards you don't understand. Can you add more information on what you are looking for.

It is an absolute rating system, i.e. the rating can be used to determine the winning odds of a specific player against another specific player. The system has been worked out according to statistical and probability theory.

The rating is an integer, the minimum is 0. The starting rate of an unknown player is 0.

Ratings are amended each time you finish a game, by adding or subtracting a small amount from your previous rating value. The amount added or subtracted depends on the result of the game and the rating of the players.

Calculation

The following formula is used:

Rn = Ro + K(W-We)

Rn is the new rating.

Ro the old (pre-event) rating.

K a constant (32 for 0-2099, 24 for 2100-2399, 16 for 2400 and above).

W the score in the event - i.e. for a single match win=1; draw=0.5; loose=0.

We the expected score (Win Expectancy), from the following formula:

We = 1/ (exp10(-dr/400) + 1)

dr equals the difference in ratings.

This formula has the property that the sum of the rating changes is zero. It turns out that if the rating difference is more then 719 points, then if the strong player wins, there is no change in either rating.
