Hi Bob, That was pretty much my question a while back, though the reason I asked it was more in reference to claims that steel wire doesn't continue to stretch after the initial settling. So far, what we have come up with is that the wound strings are at a higher tension than the lowest steel strings, and so smaller changes in tension result in larger changes in pitch with the lower tension part of the scale (even though smaller changes in tension make larger changes in pitch at lower cps). And here we'd always been led to believe it was because they stretched across the longest portion of soundboard where the most change had opportunity to occur.
