No offense Randal, but if you haven't heard of DU then you need to go back to the academy. Matched
precipitation rate applies to sprinkler nozzle output (in this case) in a given area. It has essentially no meaning with respect to the entire area being irrigated. In other words, just because you have "matched" precipitation rate between your nozzles in no way means you have a uniform PR over the entire area ..... a.k.a. DU.
