• Don't make "final" hard cuts, include your favorite multivariate discriminate in the likelihood of the experiment.

  • I told you two years ago not to be afraid of candidate!
  • No luminosity-dependent optimization of event selection.

• NP/Bayes decision gives optimal separation of specified hypotheses for a given information content.

  • S/(S+B) maps onto S/B so it is optimal event discriminator but saturates interesting region into 1-e so beware of digitizing/numerical tolerances

• I hate the CLs name. It is only a small detail in the framework I describe.

• P(D(-2lnL)<1)=68% is a terrible approximation for searches for rare decays (motivation for CLs/MFLR in early days).
