Thanks for the read – and I completely agree. xG differential is often the quickest “process vs results” sanity check. I can relate to the issue too: people get carried away when GF/GA is going in their favour because it’s easy to explain and relatable, but over small samples it can be noisy (finishing streaks, keeper variance, game state).

xGD is more about what’s repeatable – chance creation and chance prevention. I remember flagging Man United around Gameweek 6/7 based on the xGA they were conceding even though the GA wasn’t reflecting it. Fast-forward to Gameweek 11 and it looks like that has started to catch up with them.
