Out of 25 non-slam contracts only 8 contracts are shown to have positive results. They are 1H 1S 1NT 2H 2S 3NT 4H 4S. This is the case for both imp and mp scoring.  I call them "our contracts" or "Peter's 8 contracts". If it is our hand we prefer to play in "our contract". If it is their hand, we prefer them to not play in "our contracts" The first 7 lines for NS or EW are one line for each level of final contract. Each line has 5 groups of results one for each suit and a total for the level. First line is 1C 1D 1H 1S 1NT (total for level)  Each group has 2 values, the first is imp score and the second is mp score. NS each level one line from 1 to 7; C D H S NT ave IMP , ave MP;(total for level) -0.36 48.45%; -0.14 49.33%; 0.48 56.22%; 0.38 55.13%; 0.13 53.77%; ( 0.16 53.78%) -0.47 48.54%; -0.27 48.93%; 0.14 54.19%; 0.19 54.28%; -1.18 45.90%; (-0.15 51.52%) -0.70 47.58%; -0.58 47.74%; -0.70 47.53%; -0.56 47.82%; 0.49 52.67%; (-0.01 50.30%) -1.00 45.43%; -0.96 45.00%; 0.28 50.65%; 0.21 50.07%; -1.49 45.96%; ( 0.13 49.80%) -0.88 41.37%; -0.92 41.47%; -1.72 41.93%; -1.89 41.47%; -3.99 37.73%; (-1.27 41.50%) 0.58 48.97%; 0.61 49.50%; 0.13 48.04%; -0.18 48.15%; -0.80 49.68%; (-0.01 48.76%) 0.25 43.94%; 0.01 46.15%; 0.59 48.04%; 0.29 47.98%; 0.38 54.96%; ( 0.35 50.24%)   EW each level one line from 1 to 7; C D H S NT ave IMP , ave MP;(total for level) -0.32 47.43%; -0.14 49.52%; 0.44 55.93%; 0.40 55.62%; 0.18 54.33%; ( 0.20 54.20%) -0.42 48.02%; -0.26 49.18%; 0.19 54.15%; 0.25 54.38%; -1.19 46.10%; (-0.12 51.56%) -0.73 47.59%; -0.55 48.17%; -0.67 47.72%; -0.56 48.10%; 0.49 52.48%; (-0.01 50.30%) -1.05 45.18%; -0.97 45.04%; 0.31 50.68%; 0.22 50.21%; -1.55 45.54%; ( 0.14 49.85%) -0.94 41.62%; -0.95 41.40%; -1.68 42.03%; -1.86 41.31%; -4.18 35.52%; (-1.29 41.52%) 0.47 47.82%; 0.69 49.39%; -0.09 47.10%; -0.18 47.37%; -0.86 49.05%; (-0.10 48.02%) -0.38 43.60%; -0.72 46.20%; -0.01 46.08%; 0.37 47.14%; 0.15 55.26%; (-0.01 49.84%)
