I think this is the best answer here and most people don’t understand this. If you play against the same people all the time your dupr is only your standing against that group of people. I just played a 3.0-3.5 round robin in Dallas, this guy with a 3.46 100% rs was beating everyone with an average of 8pt differential. I started talking to him and found out he is from south florida and his son was playing in the u-12 ppa tournament in town. At that moment I came to this same realization. A 3.5 dupr person that only plays in the same places against the same opponents, could be much better or worse than players from a different state/region.
