We're all proud of our own individual fitness, but let's be real. If you're not a pro, you simply don't have the opportunity or the time to train day in and day out to last 5 sets on a regular basis, and make ends' meet.
Not to mention, there's a reason why even the Tour don't mandate 3 out of 5 sets format except for the Grand Slams and a few special occasions like Davis Cup and the WTF-Finals.
The WTF Finals aren't even best of 5 anymore. 2007 was the last time that was best of 5. Since the ATP completely took 5 set matches out of their rulebook, I'm not seeing USTA going to 5 set matches in league/tournament play.
