Tracy wasnt in my top 50 and 56 feels about spot on for her. Famously also won Wimbledon Mixed with her brother John and of course in tennis media now as Mum of Brandon Holt
Jeff did say earlier "Then things get tight ... at least half of #51-60 could easily be rated higher, much higher in a couple of cases."

I suspect its largely just Gameover, myself and possibly Indy following this series to unveil the greatest of all time on Tennis Abstract. But Id heartily recommend anyone going back over the list and reading the narratives - a real, loving , work of art by Jeff, its become my favourite tennis series in a long time.
Speaking for (at least) myself, I believe that there are readers of this thread that are just that, readers. Not having anything to say doesn't make us disinterested.
