It depends, some people get angry and confused out when stats tell them something they don't want to hear, others are curious as to what the underlying trends tell us. I'll admit that when xG told us last year that Ole's initial run was a freak, I dismissed it also but after looking into it xG is probably the best metric there is that's available to us plebs. Funnily enough I've had the same arguments with Leicester fans this season as xG had been saying that their form early on was massively out-performing the average both offensively and defensively, so that would suggest a correction would occur. Here we are now with them losing 4 in 6 and looking like what I suspect they are, a higher mid-table team that was on a freak run, rather than a special group of players under a genius manager.
The basic statistical data of losing only winning 30 in 31 should tell that the run is highly unusual or a 'freak'. Arsenal never recovered after the bubble was burst on their '50 not out' run. I wouldn't be surprised in the slightest if that happened to this Liverpool side.
You are correct in that xG is not a tell all metric and factors like a great goalkeeper and great attackers might lead a team to out-perform its xG longer term. Some sides in Spain seem to have. Personally I'd back City to win the title next season though as I think the data shows they're a better footballing side and Pep will get the backing to make the tweaks in player quality.
I guess as this is a United forum I won't be excommunicated for posting like this about Liverpool

It depends how you look at it. Henderson is highly unlikely to score from that position so you can frame it as lucky that he got so close to doing so, thats why it wouldn't have affected the xG positively very much.
