This sounds cool, I like the idea. I would be more interested in Dom if it wasn’t for things like “if you don’t save 12 visits, you’re screwed” and “the furious scramble in the last five minutes of the week.”

I do think, however, that in addition to receiving points for excelling in the various categories for each round, there should also be points awarded for great timesulative performance, like there is currently. Make it significant, but not the deciding factor, since otherwise there would frequently be little suspense towards the end.
