Nothing has changed for decades.
Correct. From a copy of my company documentation dated 1999,
"
Take -off Ban .... Note: Pilot assessment of TDZ RVR when practical always overrides the reported RVR or met visibility. Pilot assessment may not be practical where runways are humped or the RVR limit is high"
Why would there be the requirement to have any TDZ RVR if it can be always replaced?
The reported RVRs are for both Landing and Take Off considerations. When landing - you can't assess the RVR yourself because you aren't physically there yet.
