It may be terminology that's messing with our heads, again -- and how we laymen interpret those words.

Yes. I agree.
What I gleemed from the conversation (we didnt discuss this specifically) is that "elastic limit" is referring to the point where rate of degradation really starts to fall off. Its not a hard # or %. Different materials, lengths, diameters etc etc will have different results.
And the atmosphere at which they opperate in will impact all of this too.
It really seems like we should be useing the term "elastic range" instead of "elastic limit". Leaving "elastic limit" to reference when there is no more elasticity because it has reached, or exceeded, its elastic limit.
A gun mfg that recommends changing the springs every 1000 cycles vs 5000 just has an over all design that has the spring operating deeper into the
elastic range.
For the record:
The engineer contact I referred to works at Hughes Space and Comm in El Segundo CA. They have applications on land, sea, air, LEO/MEO/GEO satellites, as well as outer space applications.
They do not have firearm applications..... at least that he knows of
