Well the first 4 books would be 14 times each, the other three 10 times each, at least, I mean I really lost count. Keep in mind, I never had many hobbies and I literally breathed Harry Potter. Also I'm quite an experienced reader so... yeah the last 14 years were quite a time (I read other stuff too, those were just my favourites)
I did however miscalculate, that would be 86 times minimum
And the movies, well.... I have phases. E.g. within this lockdown I had five HP marathons. Now imagine that since 2011 (when the last film came out).....
