-Comments made by observing preliminary results presented in the initial session: The aN3LO/NNLO k-factor for MSHT ~0.98 and for NNPDF looked ~1 (very preliminary). The NNPDF NNLO result is above the MSHT result and so at aN3LO we may see an even larger disagreement.+Comments made by observing preliminary results presented in the initial session: The aN3LO/NNLO k-factor for MSHT ~0.98 and for NNPDF looked ~1 (warning: ​preliminary).
