I think you probably mean insulation, not shielding. But, you’re right, there are many variables involved, thus making it rather difficult to prove solid core vs stranded. Purity of metal, type of metal, type of dielectric material, break in, shielded vs non shielded, directionality, geometry, cryogenically treated or not, etc.
