You have it backwards.

The sharper termination allows the string to pivot. I posted an except 
on all this from Ed's book on this a while back.  Its in the archives. 
There isnt a lot of guesswork involved here, and the lower inharmonicity 
is not a goal in-itself... its just one of the results of the sharp 
termination.

    So what you're saying is that a less sharp termination allows the
    string to
    pivot and, in effect, influences the stiffness factor of the wire. 
    I would
    think that as long as the situation was stable that the measureable
    difference would be small, the audible difference probably
    insignificant.  A
    more rounded or flatter and wider termination also has the potential of
    creating an oscillating string length which might have a greater
    negative
    impact, i.e. falseness.  It would be my guess that as long as the
    termination was stable, that is not oscillating to the point of
    falsenss,
    that any increase in inharmonicity due to the ability of the string
    to pivot
    would be relatively insignificant, meaning even if you could measure
    it, in
    practice you probably couldn't hear it.  For me, the importance of
    the shape
    is to avoid falseness, leakage and produce long term stability.  These
    issues I would rate as much more important than any inaudible
    differences in
    inharmonicity.
