You can find the updated dosumentation in: http://www.slac.stanford.edu/~asarti/recoil/sys/theor.html (linked in the items web page) I've added the reconstructed and true MX (after all analysis cuts) distributions. A really minor effect (bias) can be seen in the non resonant integral for the reconstructed mx. For what concern the true Mx after the selection the agreement B0/B+ and the agreement nonresonant/hybrid are worsened (expected bias due to analysis cuts). All the observed behaviours are compatible with what expected (even the small discrepancy around 1.5 GeV for hybrid/nonresonant MC). Let me know any further test that you'd like to see.
