Well look away now.
Our win precentage between 2009-15 for the mainstream footy days shows that we'd rather play on Sundays (68.97%), then Saturdays (55.00%), but definitely not Fridays (30.77%). Although the sample size for Fridays isn't huge. But we have lost the last four Friday night games. Overall between 2009-15 our combined deficit points is 199 (which is about -15 points a game). Of course we got belted already this year too, so that has increased to around -247 points at about -18 points average.
