XG stats in filters
-
Hi folks
Hopefully not a stupid question...
What are we actually looking at if we select as a filter Overall>Average>XG and set values for example between 2.5 and 4.5 (last 10 matches).
For Sunderland vs Man City today, that value is 4.02. Does that represent the average XG for both those teams in their last 10 matches?
When I looked at the H2H average XG for the two teams, the value returned was only 0.15. Does that mean? Really, no goals expected in their game? For that, I selected last 10 matches. Does that look at their last 10 H2Hs? Selecting last 5 returns 0.3. Still suggests in the H2H, there's very few goals expected, but that can't be right, can it???
Sorry for all the questions - I just want to make sure I know what I'm looking at to base decisions on!!
Thanks

@James-Menhenitt Think of xG less as "expected goals" and more like "expectation of a goal". It's basically the probability that a given shot made by the average player will result in a goal.
A value is given to each shot based on tons of factors, including distance and angle to the goal, type of shot (header, volley, etc), position of the keeper, the type of pass that led to the shot, etc. The xG values for each shot are then added together to give an xG value for the whole match.
The Overall > Average > xG in the software then takes the last 10 home matches for the home team and the same for the away team, and gives you the average xG figure per match over that match history.

@Martin, thanks Martin
I didn't trade it as I wanted to make sure what I was looking at, but the XG was up there with what the overall was, just no actual goals!!
I'd be just as interested in Adam confirming what the Overall XG actually means asw well, so thanks in advance!

@James-Menhenitt hope you took it's advice on the H2H!
I'll tag @Adam on this but it will be to do with the fact that they have not played any games against each other in the same league for donkeys years.
