This was my first series of loop tests because a lower leg running on the ground (or even under) sure simplies the design. My tests indicated that if the total conductor loss is as low as 0.8 ohms Rac you will definately see major losses as you reduce the earth spacing below 5ft. Possibly your soil conductivity is less than mine and your loop conductors have a high Rac, but I will bet the losses for the damp rich soil in the middle US farmland will have a much more pronounced effect at close spacing than mine.
