Curiousities from PlayOK hands

Don't ask me to explain this right now.  And it's probably not meaningful on its own.  It was easy, that's all.

contract 50 happened 352 times
contract 51 happened 131 times
contract 52 happened 148 times
contract 53 happened 192 times
contract 54 happened 131 times
contract 55 happened 129 times
contract 56 happened 76 times
contract 57 happened 48 times
contract 58 happened 55 times
contract 59 happened 27 times
contract 60 happened 233 times
contract 65 happened 397 times
contract 70 happened 239 times
contract 75 happened 109 times
contract 80 happened 56 times
contract 85 happened 23 times
contract 90 happened 3 times
contract 100 happened 2 times
contract 105 happened 1 times
contract 115 happened 1 times

This is more interesting.  Obviously, 50 has a big spike from saves and dumps.  Hmm, next thing to do might be the success rate for each contract level...how many of those 70s and 75s were flyers?  Either not pulling 20 or missing by, say, 10+.

contract 57 happened  bid 48 made 91.7%
contract 58 happened  bid 55 made 80%
contract 59 happened  bid 27 made 96.3%
contract 60 happened  bid 233 made 84.5%

contract 70 happened  bid 239 made 84.9%
contract 75 happened  bid 109 made 74.3%
contract 80 happened  bid 56 made 87.5%
contract 85 happened  bid 23 made 78.3%
contract 90 happened  bid 3 made 66.7%
contract 100 happened  bid 2 made 50%
contract 105 happened  bid 1 made 100%
contract 115 happened  bid 1 made 100%

OK, so the 50 failure rate includes dumps and saves, so it should be low.  I suspect 52's relatively high fail rate is in part from auctions like 52-pass-pass-pass and pass-52-pass-pass.  75 looks like it's the favorite over-optimistic bid spot, or maybe the point where the opponent wakes up more often.

Seat statistics

seat 1 declared 490 made 85.7%
seat 2 declared 633 made 83.3%
seat 3 declared 549 made 86.5%
seat 4 declared 739 made 82.5%

Seat 4 is the dealer. Makes sense dealer takes the most contracts; he takes the bid in pass-pass-pass-50 and pass-50-pass-51. These are both fairly common. I think 3rd seat takes more bids than 1st seat because he can jam-bid after a meld bid by his partner, OR after pass-50. A meld bid by 1st seat allows 3rd seat to act when otherwise he might not, as well. If 1st seat bids 50, 2nd seat OR dealer can give meld; the auction is much more competitive. If 1st seat gives meld, 3rd seat can block the opponents.

Also note that 3rd seat appears to have a slight accuracy advantage. 2nd seat and dealer...their make percentages get dragged down a bit, by the save auctions.
