You do not modify the V1, the V1 will always be your actual GW V1. In fact You do not modify any V speed, You simply rotate at the RTOW Vr or actual Vr +20 kt whichever is lower. In my operator SOP the PM calls "rotate" at the bugged Vr and the PF initiates the rotation at Vr+20 kt (provided no WS is encountered etc..). I have used the above supplementary many times and given the weights we usually operate at I have almost always been within actual Vr+20kt when looking for the RTOW Vr.
