The math, as displayed in the vector diagram, makes it clear that measured solenoid resistance is not so very material to actual performance in a system, since the inductive reactance in the scenario you supplied allows for operation without overload, even if you had measured zero ohms solenoid resistance.

(of course, dead-shorted solenoids aren't going to generate the magnetic field that is responsible for inductive reactance, but a below-spec solenoid resistance, in combination with the usual amount of inductive reactance, would not prevent zone operation)
