Does anyone know how Citi handles Gym Memberships as far as category?

I created a spreadsheet of my charges/TYP earning from my Citi Premier in the last month statement, and it was all in line except some $50 total (i.e. my 1X was 50 lower, my 2X was 100 higher).

After scanning through, it's definitely not any of my restaurants.

That leaves Entertainment. Now, for Gold's Gym they said EntertainmentMEMBERSHIP CLUBS-SPORTS,RECREATION. However, this was one of the few things that tallied up to $50, and even the rounding would make it correct. So I think I've narrowed the culprit to these charges.

But my question is this: even though it's Entertainment, do gym memberships actually COUNT as entertainment?
