We extend the considerations of \\cite{Baikov:2018wgs} by two more loops, that is for the case of 6- and 7-loop correlators and 7- and 8-loop renormalization group (RG) functions. Our predictions for the ($\\pi$-dependent terms) of the 7-loop RG functions for the case of the $O(n)$ $\\phi^4$ theory are in full agreement with the recent results from \\cite{Schnetz:2016fhy}.
