Some minor things to fix

Oh, I agree it looks awkward. I translated it without the brackets, but including the meaning of the brackets into Dutch. Just don't know a proper rephrase in English :)

Maybe "at highest" would be better rephrased as "at most", but I'm not familiar with the context.

I guess this is a statistics page for reviews per page (now, if I knew exactly what a review is). It shows the mostly reviewed pages, that have been reviewed to the specified level. So, my best guesses are:

"This page lists most reviewed (to the specified level) pages." "This page lists pages that have been mostly reviewed to the specified level."
