Well, I'm not sure this is the right way of looking at it. Nobody knows
what the electron is doing when you're not looking at it. Nobody knows
if electrons have a fixed path or not. People only know that if there
*is* a fixed path, you can't tell what it is without looking at it.
Nobody knows if electrons have a fixed position at any given time.
Certainly every time you look, they do. Equally certainly, for the math
to come out right, you have to assume they *might* be most anywhere.

There is no effective maximum distance. There are only "fluctuations"
that are impossible, and "fluctuations" with very low probabilities.
(It's the "impossible" bits that keep all the electrons from falling
into the nucleus.)

Yes, that's basically what the math says.

Yes.

I think you're looking at one experiment that gives very un-common-sense
results, and trying to come up with a common-sense explanation based on
popular understanding of what's known about how it works.
Any explanation you give for the "two slits" bit has to deal with
quantum erasure and delayed quantum erasure, for example.

I'm not sure what you mean by "diffusion" here. Diffusion happens
without wobble or loss of velocity, so you might be talking about
something else. There is no "effective diameter of possible
fluctuations" if I understand what you mean by that properly.
