What is the frequency of the "Multiple Spark"?  At really high RPMs, the 
multiple spark may not even be an advantage, since combustion happens so 
quickly.  Has anyone out there looked into this?

My understanding is that the newer MSD multispark systems provide a series of
sparks at lower rpm and one hot spark at higher rpm.  I have no clue as to how
they do this.  I'm not sure if there is a sudden switch in modes at a certain
rpm or if they gradually taper off the number of sparks/revolution till they
reach a limit of 1.  I'd think the latter would be a better deal.
Thunderstruck...
