I think Best-for-Fritz is a good description of this rating list. All those
versions of Fritz 8 are roughly about the same rating and one can infer that
they are basically the same program with perhaps a few alterations and bug
fixes. Listing them separately has the effect of pushing all Fritz's competitors
down the list into artificially low positions. IMO.
