With the Tipping Comps, how do you guys feel about tipping a margin on each game?

By that, I don't mean the exact margin like 8 points or 17 points or 45 points or whatever. I mean the margins that are commonly used by the bookies: For League and Union it's 1-12 & 13+ and for AFL I think it's 1-39 and 40+. I think we should pick margins on each game and if you pick the winning team by the correct margin you get 2 points, if you pick the winning team but get the margin wrong 1 point.
