I can't say whether it should or not, but it does. Not long ago, trying to come up with a mechanical impedance formula for plain and wound strings, I did some beam deflection experiments on wound strings with and without the wrap to see how much stiffness the wrap added. The modulus of elasticity of the copper wrap turned out to be just a little over 0.003 that of the core wire by my count. That's why changing the wrap sizes has so little effect on inharmonicity (ends being left alone), when it has so much effect on tension. A change in core size will have far more effect on stiffness (and little on tension), and therefor more effect on inharmonicity. Ron
