Player with most tournament finals without an actual win?

Hello everybody!

I am a huge fan of tennis statistics. After my search through the internet didn't worked out, I thought about asking my question here:

Do you know which player made the most tournament finals without actually winning one?

I don't mean solely grand slams. I mean all Tournaments on ATP-level, including grand slams. I also want to specify that a player who has, for example, 10 final appeareances but won just one, doesn't count. Although it would be nice to know who has a very low win-percentage. (from the more recent players, Mannarino had kind of a bad one until his 3 wins in 2023).

Every answer is appreceated!
