I have several F200's.
I read somewhere that Matts grew up in a small town in Sweden. Very unlikely place to be from and become number one in the world. He learned tennis in the parking lot of his father's workplace. (They set up a net in the parking lot. Reminds me of the Serbs (Joker, Anna and Tipsy) playing tennis in the drained Olympic pool in the winter time. Crazy stuff.
As I recall, he quit sort of young (like Borg) and then came back some years later (like Borg) and didn't do so hot (like Borg.).
And yes, those guys would own a 5.0, they are so consistent and effortless. No coincidence they were so highly ranked. They are in a completely different world tennis wise than you and me.
