... who cares about astronomical values?
Apparently you did when you stated that coiling will increase inductance without reference to the amount of inductance created or the influence on audibility.
You continue to completely miss the point by performing your theoretical gyrations of inductance in a vacuum.
Et tu.

The paper you referred to above makes not one reference to whether any of the measured interactions were audible under either normal or test conditions.

The ability to measure a difference does not equate to something being audibly better. Not too many years ago amp makers were chasing incredibly low distortion numbers yet amplifiers that did not measure as well sounded better.

Likewise, nothing you've said above indicates that coiling a speaker wire would be audible. Your position on the situation is just as much a "theoretical gyration" as mine unless there is a portion of this thread that is not available for my viewing.
