Yes, the ground strike caused the energy in the secondary to clamp down
and drain faster (the energy contained in the secondary at that moment
in time). If this occurred during the pri to sec transfer, then there is
still energy being coupled to the secondary. That energy will continue
to transfer at it's rate determined by the mutual inductance which is
where we derive the coupling from.

Yes, the quench time is faster (if the system is normally something
longer than 1st notch), but the rate of transfer remains the same.

Ok, the total transfer time is based on the transfer rate and the number
of times this transfer occurs. If we shorten the number of transfers,
the total transfer time will be shorter. The rate does not. Terminology
differentiating these two separate aspects.
