Does your wristwatch go as it is judged over a nonzero
length path in the real world?

IOW the path has zero
delay and the watch calculates what to show you by
the distance you are from it.

Do magnetic and electric paths have the same delay
and attenuation in the real world?

It is called CYA. AE was well aware of Webers work
and likely had plenty of insight why Weber's equations were
inherently relativistic.

<< 8 - 14th October - Einstein fails the entrance exam for the
Swiss polytechnic in Zurich despite outstanding results for maths
and science (he was two years below the normal age of 18.)
However the mathematical and science part of his exam impresses
Professor Weber enough for him to invite Einstein to attend his lectures.
