Grandmasters who don’t castle as frequently?

Random question, but can anyone provide results for this query?

GM castle % = (all of the GM’s FIDE-rated games where s/he played O-O or O-O-O at any point) divided by (total number of the GM’s FIDE-rated games)

I’ve noticed Magnus eschews castling seemingly more frequently than other GMs… interested to know if he’d be #1 on a sorted list of least frequent castlers.
