What is Ghost-Rating?
Ghost-Rating is an unofficial rating system developed by TheGhostmaker as an alternative to points. It intends to provide a more accurate measure of the ability of players, and also to give a better idea of how well people are doing compared to previously. The original version was developed in 2008, and based on the Elo used in chess, however the algorithm has been improved several times since then.
How does Ghost-Rating differ from points?
There are several differences between the two systems. Unlike points, Ghost-Rating takes into account the ratings of your opponents, so for instance if you beat some very good players, you will get more credit than if you beat weaker players. Ghost-Rating treats all games with equal value, rather than allowing one 1000 point game take much greater weight than lots of 35 point games in the ratings. Ghost-Rating doesn't top up your rating if you drop below 100, so it will give players who aren't above 100 points a way of judging how well the are doing, and it doesn't have inflation, which means that you can compare your rating now to your rating six months ago to see if you've done better.
How do I find myself on the list?
Depending on your browser, use either F3 or Ctrl+F and search for your name on the page to find where you are on the list.
How do WTA and PPSC work in Ghost-Rating?
PPSC works just the same in Ghost-Rating as it does in points, in the sense that if you want to get as good a rating as possible, you should aim to maximise how many supply centres. Similarly, WTA works the same, so you want to get a draw or a victory to maximise your rating. In a particular game, points and Ghost-Rating have exactly the same reward systems, so you don't have to choose between the two.
Do limited press and variant map games count in Ghost-Rating?
Both these types of variants count, however they are weighted down to take into account that they are often less well balanced etc.
I have fewer games in Ghost-Rating than on webDiplomacy- why?
The Ghost-Rating list filters out games where the game ends before Autumn 1903. This is because these games cannot be won without CD, and before the cancel feature was introduced, people used to 7-way draw games that they wanted to cancel for whatever reason.
Can Ghost-Rating be integrated into webDiplomacy?
The biggest barrier to this happening is that it needs to be programmed. If you know php, and want to see this happen, please contact TheGhostmaker about doing so, as he would be happy to help.
