The 10-12 notrumps did seem to work well, in the sense they usually got to the right contract. However in looking at the Meckwell experience with 10-12 (sometimes 9-12 outside the arms of the ACBL) what was striking was that the mini notrumps did not deliver a lot of IMPs. By contrast, the 14-16 notrump, with frequent upgrades of 13 counts, reached the contracts expected and also delivered many IMPs. In particular, it seems it is considerably harder for expert opponents to judge their game chances against a 13/14-16 notrump than a 10-12 one.
