Actually the positive result of your friends modifactions came through a reduction in line loss. Line loss is not something recognized by many in the engineering field, with exception of those dealing with high voltage/distribution lines. Thus, the reason you will see capacitor banks mounted to power poles along distribution lines. My belief is because formulas and numbers don't work out right for engineers, but it's a proven fact when measured by amp meters at the load, and watt meters at the power source.

By using a capacitor you are also improving the power factor of the load, and the over-all savings can be substantial when dealing with large inductive loads that are located a considerable distance from the panel/power source. All conductors, regardless of type present a certain amount of resistance, and the longer the distance the greater the voltage drop.
