Though I have to credit you with the correct observation of the word "reported" in the title, it doesn't change my opinion.

Met visibility and RVR are two different quantities and you can't simply compare one to the other as if equivalent. JAR-OPS 1 divides the circumstances into two:

1) those in which a met vis to RVR conversion is not permitted at all
and
2) those in which met vis (and the text, as opposed to the title, does not use the word "reported") is factored according to the conversion table.

There are no circumstances in which met vis should be compared with RVR by simply ignoring the factors in the table or pretending that they are all 1.
