I know its off topic but just for a comparrison .
If you go to ANY major soccer league in England and Europe you will find these figures give or take a %point or two
Home wins 44%
Away wins 28%
Draw 28%
and that is consistent even going back a few years.
You get some odd figures if you start digging round say 3rd div teams and some
weaker leagues .
Have we got any consistency of figures say in AFL or NRL
