Interesting, thank you. And yes, a stronger spark can improve performance and efficiency, even if you don't have a misfire. The reason is because a larger, stronger spark will ignite more air and fuel at once, which means faster flame propagation. This is more important at higher RPMs where there isn't as much time for the air/fuel mix to combust, but yes it can make a difference.
