Luke,

When the coupling is decreased, less energy is coupled in the
initial full transfer of energy from the primary to the secondary.
If there were no losses, then a looser coupling would simply
slow the transfer and would not increase the losses.  But because
the system has losses, the losses do increase with looser
coupling and slower energy transfer.  The energy that doesn't
transfer doesn't feed back to the cap, rather it's simply
dissipated in the losses as heat, light, and radiation.
