Another critical matter is the setting of the load reactance. The
reactance is many times larger than the resistance, so a slight error in
setting its value will result in a large difference in load current and
therefore load dissipation. For example, if the segmentation is changed
from 100 to 50 segments/wire and no other change is made to the model,
the reported load power becomes 0.3917 watts. . . .

Correction: That should be 0.3917 mW. The error doesn't alter the
conclusion.
