I see that nobody has updated the page, but make sure you're using the Ring of Brodgar wiki viznew linked you (or a clone of it if you're using one that is a translation and hosted elsewhere).
There may be a few other pages that are marked legacy like this that are still pretty much the same information and hasn't changed since legacy.
I went and updated this one as best as I can recall without digging up details. (I don't recall specifics changing on P*E, it's still about 80, and the terrain list was outdated.)
