The sound of a piano is, as we all know, a very complicated system. The inharmonicity does not come from the piano wire alone. If you bow (if your violin bow doesn't fit, rosin up a scrap of old felt) a piano string, the inharmonicity will be less than striking the string with a piano hammer! The formulas we have for inharmonicity in a piano do not show these things; they assume the piano will have felt hammers, bridges and a soundboard fixed on all sides. How much these other things influence inharmonicity, I don't know, but the image we like to hold in our mind to understand it normally simplifies things too much.
