I love football ratings as the season is beginning thought i would post up my numbers

I score the ratings
1. for the win
2. for the draw
3. for the loss
4. for goals against
5. Goals for
Ratings can be suspect and have flaws would love to hear from people who use this way to trade or for betting purposes.
I like to use the last 6 games overall to make a clear pick but there are many ops.
I cannot post every day as i have work commitments but will post in when i can.
Look forward to any feedback ?
