But then why doesn't the same thing work on your coil,
with 282K, 3pF, and 111kHz?

Mine favors the pos peaks as well, which agrees with 
the published literature on polarity preferences of 
sphere-to-plate spark gaps.

Keep up the good research, you're definitely 
pushing the knowledge front in the area of 
arc creation and maintenence for TC's.
