I don't disagree with you, but it's not clear to me how vital the "Mark as Reviewed" function actually is to the GTD weekly review... Why would you need to mark anything? What the function seems to do is take a project at the top of a "Next to Review" list and shove it to the bottom of the list, without the bother of assigning arbitrary start or due dates (when all you really want to say is "not now"). Regardless of how you end up using that function, it seems to me that, given that a single action list is essentially a list of single action projects, it makes little sense to shove that whole list to the bottom. Especially if you aren't bothering to sort related single actions into separate lists.

I guess what I'm saying here is that I don't think what anyone has written here is wrong, per se, but none of it really seems to me to explain why this function behaves the way it does.
