It doesnt really relate to ratings at all.
It just means that Fritz is playing and will offer you the equivalent of a pawn odds sometime during the game.
You can't judge what that equates to as a rating, as Fritz in friend mode is a different engine than the full works, and also its rating will depend on your PC and specs etc.
For example, what rating does it correspond to when the computer plays with -100 handicap? Any experience or guess?
