Betfair isn't like that, as they aren't bookmakers. Betfair exchange betting sets you against me, your money against mine. They just take a percentage from the winner. They have been shown, in study after study, to be astoundingly accurate. Accurate enough that in a paper from Zurich University, they show that a viable and profitable betting strategy is blindly to bet when bookmakers' odds exceed Betfair's. (I STRONGLY recommend that anyone interested in odds and betting downloads it free from http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1503350 )
I also feel, however, that 42% has a more reasonable ring to it. And it's not bad at all.

Bedtime reading, thanks!
Aside from all this, I feel very positive just based on our defensive record, which boasts some wonderful stats when we're at full strength.
On stats, a ratio of chances created to shots allowed would be interesting to see. Over a season that would be a great performance marker to compare to other clubs around us.
