I understand that aspect, but I am still confused about how the test was
derived and the theory behind it.

CJ,

Basically the coupling (K) determines the rate of voltage rise in the
secondary coil. A low coupling will mean a relatively slow voltage rise and
poor energy transfer, because the primary rings for longer and wastes more
energy. A very high coupling will mean a fast energy transfer, but a great
potential difference in the secondary. The fast rising difference between
the top and the bottom of the coil causes the racing arcs. The trick is to
couple as tightly as possible without racing arcs.

Best Regards,
Jason
