Fritz and the previous versions offer the possibility of calculating Elo ratings retrospectively. The Elo system was introduced in 1970.

 

So it might be interesting to calculate retrospectively a rating for players whose career had run its course before the introduction of the Elo system.

 

This function can be found in the database window under Home – Database – Rating.

 

If the Start list is to be calculated, a database is requested ( Default.elo ). This database must be set up afresh. To do so, click on the button “Create new” in the file selection window. All other functions access the value of this file.

 

In order to calculate the following steps are required:

 

1. Select the desired games

2. Calculate a starting rating list

3. In the dialog box “Elo list” you can do any fine tuning considered appropriate.

4. After the settings have been defined by the user, you can save the Elo list.

5. For the next step, you can get the ratings calculated via "Set Elos in games".
