FE, what exactly are you looking for? I'm confused.
Relevant, means just that.. wherever the RVR is quoted at that point of the runway, touchdown, midpoint, stopend.
For take off, the relevant RVR will refer to the initial part of the take off run, I cant see why you would need a clearer definition than that.
Maybe I am missing the point here, but we seem to be re-inventing the wheel?
