T2 - the argument is semantic to some extent, and revolves around the fact that a pilot obviously CANNOT assess the mid and stop end RVR so that has to be 'provided' but can assess the touchdown RVR. I don't think one can interpret the poor wording of EUOPS to distinguish any firm intent there. My belief is that IF they intend it to be a 'provided' RVR only they would have said so clearly eg 'IRVR'.
My modus operandi, however, was that I would tend towards assessing only if the visual distance was LESS than the required. I don't think I would have even taxied with any RVR of less than 125!
