% shots efficiency

[Buffs Mad]

Shot efficiency is, as you know, the proportion of goals from Shots on target. Goals are what you know they are. Shots on target are attempts on goal from open play that either result in a goal or would have done if it were not for a GK save or the last defender. FKs that are 'on target', whether its a goal or not are not counted as Shots on Target and 'Goals' that would have occured were it not for the intervention of players other than the GK or last defender are not counted as shots on target - they are 'off target'. (The sports statistics company Opta have some nice statistical definitions).

The upshot is its difficult to analyse those stats at face value without doing your own extra analysis of FKs and other events.

Even without that difficulty there would still be further difficulty imo determining if it was defensive prowess (or negligence) or striking negligence (or prowess).
