Thread title ought to be changed. Fed has not broken the all time weeks at #1 record.
The Open Era record, yes, but not the all time record.
1. Pancho Gonzales- 364 weeks
2. Bill Tilden- 330 weeks
3. Don Budge- 303 weeks
4. Roger Federer- 299 weeks
He ought to pass or at least tie Budge in the next few weeks, and may tie Tilden next year. Gonzales will be tough to catch, but not impossible.
I think in those days there were only 5 players on the entire tour. Respect though
