slightly eccentric

[gfish]

I just measured with a micrometer, and my wedding ring has developed an eccentricity of 0.3303 (24.4mm x 23.03mm). Which is rather odd, because I always take it off when I'm doing the kind of things that would tend to crush small loops of soft metal.

Doesn't eccentricity imply that your ring is a perfect conic section (and therefore a perfect, mathematical ellipse)?

I'm thinking it probably just gets that way through years of wear. And it probably wasn't micrometer-level perfect when you got it anyway.
