Tks. Good article

Is total xg at the end of the game just the total of individual xGs?

E.g if Celtic had an xG at the end of a game of 1.5 that could be ten shots with an xG of 0.15 or 2 shots with an xG of 0.8 and 0.7

If that's the case should xG at the end be divided by no of shots?

Tks again

Hello Conor - you are correct. A main distinction people will make is total non-penalty xG vs inclusive of penalty.

xG per shot is the simple arithmetic calculation you describe and is generally considered as average chance quality.

Another main distinction people will make is xG from open play vs set pieces.
