the probe to measure the Q.

Of course, you can account for the probe loss when you do the math. Or
leave the probe disconnected during a ringdown, and add it after some
delay to see how much energy is left in the system.

If you have to "do the math", you might as well just calculate the Q
from first principles and forget the "measurement".

How can you calculate Q from first principles? 3D EM simulation?
Quantum mechanics?
