Actually pretty consistent really. Just not in a way that makes sense.
Round 1 - win away
Round 2 - lose home
Round 3 - Win home, but GWS, so not travelling opponent
Round 4 - Win away
Round 5 - lose home
Round 6 - win away
Round 7 - lose home
Round 8 - win away
Round 9 - win home
Round 10 - win away
So taking out the local derby they are 1-3 at home and 5-0 away. They should still win, but for some reason they are a much better side away this year, then at home.
