It's not that I don't know how much to give each team. What I'm looking for is which melbourne teams have a genuine home advantage vs other melbourne teams. To do this I just need to look at how teams perform specifically at that ground.

E.g, if Team A is strong at TD but Team B isn't, then Team A should get the home advantage. If Team B was just as strong at the same ground, it should be classed a neutral venue.
