Are the default rotor head flows assuming a 360* arc?


I know I should do a catch cup test and I’m working on feeding my fat cats to collect some more containers. Until that happens… are the rotor head nozzle settings with 1 in/hour assuming a 360* arc and no overlap? I have a couple zones where each head is 180* or less of movement before I account for overlap of neighboring zones or the fact that some heads in the same zone are <30’ from each other and overlapping nozzles on the same zone.
