"Over the past five games Portland is posting a 1.4 goals per 90 goal scoring average, but according to FBref they have posted just 0.94 expected goals per 90 over that stretch. While xG can be noisy and sometimes not definitive"

Stat question: at what point does xG stabilize? I know it's pretty much useless as far as single games (No, really - it is! Despite everyone using it that way! Don't use it that way! Way too much noise!), and five games seems like a somewhat small sample, although better. But is xG better looked at a season at a time? A half season? I've never really known and am curious.
