It is, but such a tiny data set

Thousands of examples should be used to calculate xG and no great use if it’s team specific.

0.79 is used for the Opta model

Penalty Kicks

Each penalty kick is worth .79 xG since all penalty kicks share the same characteristics. Comparing a player's goals from penalty kicks to their penalty kick xG can indicate a player's penalty kicking ability. Likewise, we can do the same for goalkeepers in these situations.
