It doesn't need to be at field capacity, and without direct measurement, there is no way you can determine that for sure. Also ignore boots, as his comments are rarely anything but TIC. If you have a 70 x 35 with sprinklers at each corner and two in the middle at 35', that is perfectly acceptable. If this is true, there is absolutely nothing wrong with the sprinklers other than perhaps running the two zones together impacting nozzle performance.
