In today's common game:
One of the legitimately top players (well over 10000 MPs) passed the East hand in tempo. Afterwards, he said he was planning out the auction and looked down to see that he had passed.
Of course, it never occurred ...
-170 was average for us as well. One person in game (making) and one person in 3♠ (down 1--???). All the rest were in part scores and presumably played for the drop. None of the South players would have made any calculations.
