it'd behave basically the same as a single thicker strand

no, it would be different, it'd peak sooner,
but not neccessarily higher

muliple joins could get you 2000 turns and similar performance
to 2000 straight turns but inter-turn capacitance would be much worse.

I would get a drill to turn the former and use some sort of counter to
count turns, possibly the mechanical counter from an old VCR.

Multifilar winding is sometimes employed to mitigate transmission line
effects in induction motor windings designed to be driven by IGBTs with
sub-microsecond rise times.

is, I presume, that one comes a little more expensive, but is more
durable; the other is a cheaper thing, but the moths get into it."

Like a capacitive discharge? Ed Gray motor winding?

While the original topic was coil winding, this part of the thread has
gone off-topic and diverged to the point where what's being discussed is
the efficacy of bottom and in-line posting VS top posting.

Consequently, since my comments address top, in-line, and bottom posting
they are relevant.

Isn't comfort and lack of confusion in communications what we should all
strive for?

I've relocated your post so that it follows my earlier one in order that
you might see how much more natural the flow is, chronologically, using
bottom posting.

Just think (if you can) how much easier someone coming across this post
for the first time would find it to understand, reading it from the top
down instead of having to jump about trying to stitch together seemingly
unrelated pieces of quiltwork.
