The program prompts you for a file name. If you use an existing Elo list, its contents will be overwritten.
If there are not enough games per player in the database, the program informs you, and does not calculate any ratings.
The Thompson algorithm calculates relative playing strengths. It assumes that the average rating of all the players in a rating list is 2400. This will normally not be the case. To get correct practical ratings, it is necessary to rescale or gauge the list by adding or subtracting a certain percentage from each player. The best way to do this is to take a very stable player with a known rating, and add or subtract an offset to make the rating equal his real rating. The program will then adjust the ratings of all other players accordingly.
3.10.3 Viewing the Elo list
At the bottom of the Elo list window there are a number of buttons. They allow you to sort the list alphabetically, according to ratings or number of games, etc.
Here are what the buttons in the Elo rating display do: Sort A-Z: Sorts the list alphabetically according to the players ' names. Sort Elo: Sorts the list according to Elo rating( default). Sort games: Sorts the list according to the number of tournament games. Delete: Allows you to mark players and remove them from the list.
Gauge: Allows you to rescale or gauge the list by adding or subtracting a certain percentage from each player.
Clip: Copies the whole list to the Windows clipboard. You can then paste it into a word processor or spread sheet.
