What is Paeng all time high average score?

There's no publicly available data on an "all-time high average score" for someone named Paeng. To answer this, we'd need to know:

* Who is Paeng? (This is crucial. There are many people with that name.)

* What context are we talking about? (e.g., bowling, basketball, a specific video game, academic tests, etc.) The average score depends entirely on the activity.

Without this information, the question is unanswerable.
