SG - The anatomy of the spark?



It seems to me that some of the easiest ways to improve coil output 
performace can come from changes in the spark gap.  I'm no expert and would 
like to know more about what happens in a spark gap.

In a perfect world how would we want the spark gap to act?
What is the resistance of a spark gap when it conducts? Can this resistance 
be reduced?
What is the diameter of the arc in a spark gap, is it bigger with more 
current?
Quenching, From my understanding, quenching is act of "Blowing out a the 
spark in a spark gap.  But I don't understand why is so important.  If I 
"Blow Out" the spark  won't I prevent the capacitor from dumping ALL of its 
energy into the primary?  Or is it the act of quicky turning off the current 
in the primary for a sharp collapse in the feild in the primary that is so 
important?
Is it possible to over quench?
Also, can some one give me a simple understanding of "Ringing" in the 
primary.  I get the feeling that Ringing is the oscillations that occur in 
the primary tank circuit when the Capacitor is discharging through the gap.  
If I'm correct no explination is needed.  However, what I confused about is 
when the capacitor is discharging into the primary what is happening to 
power of my NST going into the cap?.

Thanks
Bob
