Sorry tom, that's not how it works.  THe coil is charged to max. flux
every cycle.  When the field collapses, the electronics have to jump the
path of lease resistance, (the plug gap).   If this is bigger than normal
where does the energy go? In to the coil as heat.   Smaller the gap the
less is given off in heat.
