One minute zones wouldnt even come close around here. It doesnt add but maybe 1 minute to pup wires three at a time but you save alot more time than you spend. If I know where a manifold is I go to it but around here there are hardly any manifolds most are pvc spread throughout the properties. Most around here are 1 acre or more and 8-12 rotors per zone usually 4-5 minutes for first zone and a couple each after that.
Like I said it may not work everywhere, you need to come to the beach.
