Very interesting words you assembled. Regarding your comparison of pulsars with lightning pulses, although I don't understand your explanation of the pulsing real well as yet, it reminded me of Thornhill's statement some years ago, I guess, if I remember right, that pulsar signals trail off much like lightning signals do.
I just looked up pulsar signal images and found something that might be interesting, so I'll see about posting some of that shortly.
A site on the Handbook of Pulsar Astronomy at http://www.jb.man.ac.uk/research/pulsar/handbook/ch1.html has these pulsar signal diagrams:
PULSAR
I notice in the bluish diagram that there are about 21 big spikes per second, but each wave consisting of about 7 little spikes, so that's about 150 spikes per second.
