Having read the book, I must say the rules are completely wrong. Your "RONA" matrix is skewed for the players and I think the Maze Controller was being generous with the treasure.
Also everyone KNOWS gorvilles have a greenish yellow hue, NOT a green coloration. I swear, it things like this that just burn my butt... OM&M is the only true version. This is heresy, heresy I say!!!!
Of course this is all just farce - I have to say you've done a phenomenal job on these rules. Your backward engineering is truly captivating. "RONA" is priceless. However you might actually want to try to find the book, it's utter tripe, but some of the rules might be clearer (I can't really remember too clearly, I mean I was 11 when I read the book and that was in 81 or 82 before the TV movie came out.)
