1. BTOW
   1. relative gains
   2. absolute gains + uncertainty
2. tune W-algo
   1. find optimal working point for cuts
   2. evaluate stability of W yield vs. cut changes
   3. uniformity of W yield vs.
      1. time, also timtime-in-fill
      2. bXing, ratio per reconstructed vertex
      3. eta-phi (low/high pileup fills, beam background signature)
3. identify cosmic events in final event sample
4. visual inspection of all events identified as Ws (Lego plot of all detector layers)
5. Simulations
   1. Vet algo MC/Data
   2. estimate efficiency of W-algo as used
   3. Background model for what's under the Jacobian peak
