As Robin updated only the SF (with BTV HIP mitigation) for the iterativefit (for the reweighting),
the wp scale factors remains the old one, and we just update the scale factors with reweighting.
I checked the btagWeightCSV and btagWeightCMVAV2 now have smaller RMS (while still average close to 1) on 1k events of ttbar.
