Kudos to Rich for successfully arranging such a fun evening, which again demonstrated the strength-in-depth of even relatively minor wines from the 1970 vintage (as well as the advantageous prices at which you could buy them ten years ago).
WOTN was Charles's Mz70. #2 was Tom's BN70. #3 was Alex's D83.
In terms of blind tasting, I think I recall that CPR1 got 4 points and the one of the robo-guessers 2 points. It is a fair assumption that most of the rest of us did worse than the robo-guessers.
Other than the two Mz70s which were not very similar - showing yet again what 47 years of differing history can do to wine - the surprise of the night for me was the Royal Oporto Quinta do Corval 1977, which I have not seen before, and which was comfortably the best wine I have had from that house.
