You are dead on. It isn’t really about savings in the way that they don’t magically make the grass need less water. When you adjust the PR in the settings, Rachio is still going to want to put down the same amount of water. What I noticed is MUCH more uniform coverage between heads, less susceptible to small winds (larger water droplets vs. fine mist) and less pooling in areas of my grass. True fixed spray heads are better than VAN spray heads, but you can always see areas within the arc that get way more water. MP’s seem to have an identical pattern regardless if you adjust 90 degrees, or 270 degree arc. If you had slopes, the much lower PR of the MP’s would help to eliminate runoff as well.
