I'm afraid you can't. You can get that variability watching them all or not watching them all. I could cite a 9-1 win in CL home match 2 seasons ago and 2-2 draw away - both managers watched both, same formations same teams.
I could also cite 10Q inferior teams with 20% possession making chances (and the 1 truly troll result I've had was just that - a 1-0 loss with over 15 shots on target v a ST GK) but similarly there are 14-0 wins against teams with 20% possession that didn't get the red card boost either.
I believe you should give yourself as much advantage as possible, but its not a do X + Y = win. Its a simulation. And there are patterns, patterns everywhere.....
But if not watching works for you then that's good.![]()
