My point is you cant have it both ways. The actual act of travelling accounts for cents on the dollar when considering the pros and cons of interstate games.
Having 7,8,9 times as many games with a home ground advantage every year is a massive advantage, those who complain about the GF being at The G choose to ignore the role that plays in getting them to the MCG in the first place
And West Coast have 10 games with an away ground disadvantage every year - compared to Collingwood's two or three if you're unlucky
