I can only reiterate the standard equation for this which I have 
thoroughly tested with different coils with different Fr's and at 
different k's and have yet to find wanting:  optimum dwell = n/2kFr 
where n is an odd number belonging to the set of positive integers.
The first ringup to maximum is when n=1 of course. The subsequent 
ringups all show a loss of energy to the system.
     I also did some thinking on the question of critical coupling 
last night and have come to the conclusion that it might not be 
applicable to our pulse driven coils. I'll post later on this if 
anyone is interested.
