I think the current one is better, honestly. The way these scenarios are set up, they encourage middle-of-the-road play anyhow, so I doubt we'll see a lot of scores at the opposite ends of the pole, and if we do, I would attribute it to either skill or foolhardiness, or both. In my game with jdsu, I gambled on a high-risk strategy, and he countered with solid tactics and knowledge of the game system. It wasn't luck that got him 95, so he deserved the 95 points, and consequently, the 13.
If one wanted to get ridiculous they could introduce Bayesian curves to the scores just to ensure no one without a math degree knew what was going on.
I wouldn't encourage much discussion on this point until after the tournament in any event; seems rude given the amount of work that has gone into it. Like discussing who your favourite caterers are - while sitting at the table of a dinner party hosted by your best friend.
