I really don't like the way the list is published with all the multiple entries
for each engine. Who cares about Shredder 6 or Fritz 7 when newer versions are
already published? It is like publishing a FIDE rating list with multiple
entries like Kasparov2003, Kasparov2002, Kramnik2003, Kramnik2001, etc.

Publishing such an extended list might be appropriate as a footnote or appendix,
but not as the main list. The main list should look like:

                                         Rating   +     -  Games   Won  Oppo
                                         ------  ---   --- -----   ---  ----
