PhysicsProf Steven E. Jones circuit shows 8x overunity ?

Synchro1 you can fantasize about such things.  If you believe such fantasies, then you should build a test vehicle and try it out.  Or if you prefer to cut to the chase you may observe that the capacitor gets charged up with real energy.  The energy gets dissipated.  A tiny amount of the energy remains in the iron.  In the case of the soft ferrite "U" and "I" pieces that Steven Jones is using that amount is extremely small.  Negligible mechanical work is performed each cycle.  Aside from a very minute amount of radiation, no external electrical work is done either.

That's not really true; with LEDs attached when disconnected, they will flash for a moment; I agree it's a small amount, but it is measuable and can do 'work' even if small.

What Russ Griese demonstrated is completely normal and expected.  He performed the work that went into lighting the LEDs.

Mr. Hand is in action again, not unlike turning the handle of a crank generator for a second or two.  External energy input must be accounted for in the calculations.

... by breaking the flux path and allowing it to collapse and produce a changing magnetic field through the coils... without the magnetic flux stored, there is no work... it's not just the hand.

Actually, it really is Russ Doing all the work.  Despite the high initial force, there is only a very tiny amount of energy stored in the domain rotation within the iron parts.  Russ applies energy that works against that force and in the course of opening the reluctance gap, generates and EMF that ultimately lights the LED.  The primary difference between this device and an ordinary generator is that the iron be a soft magnetic material, once the reluctance gap is opened the flux collapses and unlike a PM will not restore when the gap is closed again.
