My guess is that there wasn't any really formal means to determine the locations and/or if there was even a performance advantage. Also, I doubt it would even be possible to time them to actually fire at exactly the same time and/or offset the timing to aid in combustion - who knows how fast the flame front travels in the chamber . . . based on all the different timing conditions that happen in an engine. It would be fun to have an engine dyno and test various timing situations - including using just one or the other plug (very different locations). I think the 'cool factor' is just about the only reason to run dual ignitions - which is fine by me!
