A disclaimer this is a 15min auto ranking calculation. It's not predictive but gives an indication of how good teams are (on limited data.)
3rd column av perf ranking.
If you post the best adjusted XG figures against a team you are graded 1st. If you post the worst and they have played ten games you are graded tenth. So Leeds after 9 games have picked up 18 grading points.
The fourth column is adjusted XG difference. XG is adjusted to take out home advantage.
It's very simple, no complexity.
I am picking pretend bets based on this. It's doing okay so far.
