i did some pre-season ratings (not yet final):

Brumbies - 110
Crusaders - 77
Blues - 47
Sharks - 39
Waratahs - 37
Stormers - 34
Chiefs - 29
Bulls - 29
Reds - 10
Highlanders - 4
Hurricanes - 1.6
Cats - -1.6

Don't ask me what they mean, just putting together a new theory of mine, but will have even better and more detailed ratings soon!
