        * It might even be possible to use the powheg reweighting machinery to avoid having to re-run all the grids. This might depend on how far mtop is moved from the central value. T. Jezo and collaborators have tried this. Perhaps it'd be useful to perform a closure-test,​ but using the outermost mtop values that atlas/cms would use.        * It might even be possible to use the powheg reweighting machinery to avoid having to re-run all the grids.

-       * this reweighting would be missing ​mtop dependence in R/B+       * this reweighting would miss the mtop dependence in R/B. There exists an experimental facility in powheg, to capture these effects via a reweighting,​ but it was implemented only for DY, and rarely used. Not clear it would work here.
