That is a useful parameter, and would explain my observations.

I wonder if we could use it to equate to a tuned loop with a separate 50 ohm coupling loop, by observing the point at which the Q of the tuned loop becomes degraded as the size of the coupling loop is increased.

The Q-factor effects the coupling K value between tuned loops when the value becomes a critical, showing a flattening at top of frequency characteristic.
K critical = 1/ sqrt (Q1 x Q2 ), where Q factor of each tuned loop.?
