I just wanted to eliminate streamer growth from the equation so I was only 
studying one variable at a time. Now I can try again at a higher bps and if 
we _do_ see a difference this time, we'll know that risetime influences 
spark length indirectly through streamer growth.

We didn't measure stuff accurately enough to tell. It would have spoiled 
the holiday atmosphere :D The main improvement is that it breaks out 
directly from the toroid which looks cooler.
