Last week was a tough tipping week and this round is no different. I think this week shows some of the flaws in an automated tipping system that doesn’t include some sort of power rating that examines the quality of teams defeated as well as comparing relative ladder position. For example, the Adelaide v Pt Adelaide match sees all four systems selecting the Crows but I’ve chosen the Power. They’ve beaten two quality sides in the last two rounds, sides that played very well. Adelaide lost badly last week, and their three previous wins have been either unconvincing or against a side (North Melbourne) that was diabolical. All four systems are suggesting that the GWS/Eagles and Gold Coast/Lions games will be close ones. Personally I think the West Coast will win easily while the battle of the cellar dwellars could go either way.
