Hi Vik
Reading your post, I'm not sure just what your question is exactly. The figures you show in the table are the minimum RVR values required for those particular approaches(unless higher specified on approach plates).
To make an approach to either CAT II or IIIA you must have at least those values shown or better.
As a side note, midpoint and stop-end values to be consideredonly if aircraft speed on that part is greater than 60kts.
I hope this answers the question, but if not, ask again and I'll try again
This is written from a Flight dispatchers point of view and understanding of JAR-OPS, as we also operate to JAR-OPS.
