Hmmh. Don't take this as anything other than constructive criticism, but 'should have won but didn't' is surely a negative against the team, not a positive? Depends on the other team as a defensive unit, I suppose. I have seen lots of success with the ELO, but sometimes it is way off and I have wondered what factors were not factored in.
another thing I think is important is free kicks in promising positions. There are heat maps that show the positions of free kicks in a given game.
I'm willing to help out with noting the more obscure stats, etc.
Like, quite willing to go and camp outside Haaland's house the night before a match with some binoculars to see if he is getting any hanky panky or keeping his powder dry. That sort of thing.
