I've always found the scoring system to be a bit odd. On a Tiny Monarch it's quite easy to score 7000+ in a couple of hours, but if you take out a Huge Regent, even at top speed with a great map and start and a week of play you still struggle to come close to a Tiny Monarch without deliberately spamming for points.
It's like my 20k Regent with just 4 towns. I think that scored so low it didn't even make my front-page of wins, even Tiny Cheiftans score more. And yet a 20k on Regent is surely more of a prize than any win at Cheiftan no matter how one does it. The 20k especially is one of the win scenarios it's almost impossible to 'race to' or 'spam to'.
