Lose 15-0 to procrastinator (should have been 9-0; bots defended abysmally against him on one board). Win by 3 vs NN. Both reissued.
ETA: the +3 vs NN included +6 imps when my bidding tempted CHO to double 5C for penalties. We held it to 12 tricks (the normal trick result in clubs). At NN’s table, bots bid the slam.
I win the declare-only with 52.08%, by 1.04%. Without being certain, based on the results for everyone who completed all 16 boards, I suspect procrastinator was considerably above 52.08% for the 11 boards he played. Reissued, AA out, IMPs.
NN wins the regular challenge with +26.50, by 3.25. I got tied up and didn’t even start the challenge against AA. Both reissued
Lose to procrastinator by 25. Pro tip: in 3NT, count your sure tricks correctly, and if total is 9 or more, do not go down, especially when to do so you give up a trick when the opponents can almost surely beat you with the obvious shift. [ETA: that blunder was nonvul, so only cost 10 and would have lost by 15 had I avoided it.]
Timed out against NN. Finished either 12 or 13 boards.

I win the declare-only with 60.94%, by 2.13%. I beat AA by 35. Both reissued
Oirg wins the regular challenge with +17.67, by 11.25. I finished the wrong challenge, playing all boards against procrastinator, who played none. I played most against NN, but timed out, so I didn’t get the result on any. Reissued the group challenge; will reissue the other 2 tomorrow

I beat procrastinator 8-1, with only 2 swings, and NN by 10, with no swing either way over 7 (one push at -670, where our auctions seemed fairly automatic. Reissued
Sadly, you did not match my -530 in our match 
Probably because my double was foolish and not automatic.
