What is the point you are trying to make here? Most xG models don't consider the outcome of whether a shot was on target or not and I think that is the best way to do it. Paul Riley does his based on SoT only which seems suboptimal to me. I made a great xG model that only considers shots on target that aren't saved. R squared is 1.0 actually.
Shots like Rondon's are always going to be an issue. Just like rebounds are an issue cuz you can get a .5 xG shot then a .8 xG rebound and somehow end up with 1.3 xG in one sequence. You have to be a disciple of the law of large numbers to see it converge and even then it's only an indicator. It is better than whatever else we've got so deal with it.
