How is the secondary's inductance important to spark length? I can see it's
importance to Fr, but not to spark length (power processing maybe?). Inductance
is a factor that naturally increases with coil size - size generally means more
power applied and therefore greater spark length. Is it possible that
inductance here is mistaken as a factor due to naturally occuring mechanics?
Maybe not, I just haven't seen a reason Ls would be thought of as a major
factor to spark length, and if it is, I'd like to know why? 

The equation would suggest just increasing Ls to gain spark length. I'm sure
you didn't mean the equation in that way. Maybe you are referring to a higher Q
secondary? 

Thanks, 
Bart
