As someone who has done lots of research and testing on ignition systems on engines making 3+hp/cid I find some of the statements and facts presented here questionable.

Once the flame is lit at WOT the ignitions job is done and electricity moves at the same rate of speed in one ignition box as another.

Multi-spark ignition does have some benefits at low engine speeds especially if you have a chamber with poor burn characteristics and/or sloppy mixture.

More information is always welcome.
