John, all,

Certainly while the coil is sparking the Q will be lowered 
due to spark loading.  I think the person who was asking about
coil Q was refering to the static Q.  The secondary static Q 
depends on the secondary design.  The dynamic Q depends
of the overall design of the TC system.  A high secondary static Q
is desireable.

Tesla had many goals over the course of his work.
