Quite a few errors – and I’m afraid I don’t have the time to sort it all out. The good news is the <CG> has started using SCID, so perhaps all of the above can be fixed within reasonably short order.

Of course the above is really only meaningful if you have a merged collection of all the PGN from the zip files <chessgames.com> provides its premium members. In case you have this privilege, you can reproduce my collection by unzipping the chronological zipfiles, and merging all the pgn files, in chronological order,   into one giant PGN. This yields ~722k games (772,395 to be exact).
