8400V/inch sounds too low.  From the sphere breakdown voltage chart on
Terry's site,
http://hot-streamer-dot-com/TeslaCoils/Misc/SGapVolt.jpg, two 2.5cm (1")
spheres 0.58cm (0.228") apart would break down at 20kV peak.  Assuming
voltage vs. distance is linear (which does not seem to be the case from the
chart), that comes out to 87.7kV per inch.  Maybe a decimal place error?
