Where to put the gap?

I looked over Terry Fritz's excellent report on spark gap placement vs.
stress on the NSTs.  It's clear that putting the gap between the NSTs
and the primary capacitor is the less stressful route, but that doesn't
seem to the popular method based on most of the schematics that I have

Are there any special considerations for arranging the gap in this
manner?  Why do so many people still put the gap between the primary
capacitor and primary coil?
