No nothing wrong. Just that would be quite rigid. So if pd opens a 15-7 nt, and u have 15 points, this is a max of 32, and hence not slam going, but we all would make some try. So wondered how the equation comes into play with LTC. Maybe LTC is even more rigid. i.e on general forget distribution etc. doesnt make sense to even try for slam over a 15-7 nt with 16 hcp, cos you "rate" to have approximately 1.7 losers, so may only work 30% of the time. Well ofcourse that is why we have bidding systems, conventions, RKC etc to stop below the 6 level. This was just a curious thought/exercise. The thread can end.
