Hi Dmitry,

The coupling coefficient "determines" the full energy transfer, or 
yes, the time it takes to "transfer all" the good stuff! Certainly, 
you can get into the discussions of "is better fast, or better 
slow?". It's always better slow, but I may be confusing things.

Ideals are for theory and calculators. In practice, once you've 
achieved "the ideal", you then ask yourself, "what was so ideal about 
that"? (You have yet to do that. That's cool, as long as "someday" 
you will. Otherwise, it's not so cool.)

Sparks have different flavors. The "ideal" is just one of many, and 
sometimes, not the most tasty. If asked to perform a specific task in 
an electronic circuit, we can certainly put a value on it. But, 
efficiency for sparks? I learned a long time ago, the formula for 
efficiency is power in/enjoyment out(in watts of course) ;-) .

Take care,
Bart
