wasted spark vs. sequential ignition systems

[sraposo]

Hi!

Can someone refer to some scientific research or, at least, some dyno measurements, that shows if there´s engine efficiency variation between wasted spark and sequential ignition systems? I´m focusing specifically in results related to these two firing configurations, supposing the same other parameters (ignition discharge energy, output voltage, spark plug electrodes gap, compression ratio, A/F ratio and so on).
