Glad you agree on the empirical gap here... We have established how this "30km radius" figure has come about.

Certainly not my idea... just pointing out electrical discharges are really quite easy to replicate in labs...

is this a complete model? well no, but there are some striking empirical results that could help avoid 'strange' inventions.

Most of those slower pulsars are loners. Most binary pulsars are in exceedingly tight orbits and have very quick orbital motions, but are themselves not necessarily in the millisecond category.

I have difficulties with inventing new states of hypothetical matter, and squeezing 1.3 solar masses into a 30km object, and spinning it at 25% of C!
It's even more difficult to swallow this unimaginably heavy, ridiculously fast object will need to 'spin up', 'spin down', 'outbursts', 'frequency glitches'....
Some empirical discharge and reflected transmission experiments, as performed by Peratt above, seem.... well... a bit more real to me, than super-duper strange stuff...
Just ideas that could help, in part.... no need to dismiss
