Don't know volume/unit time yet, going out today to run a few tests to get that.
Also, can't compare a Mag to an Ultra, only one nozzle for high speed wide spray instead of the two like the Centri or Ultra. I am beginning to think I like the two better. Maybe that accounts for the difference in width (If I recall I got like 8 ft out of my Centri)
Will also look at the RPM's to make sure they are optimized.
