I need to be clearer, if for example, the TR assembly was say 12" long, and a compression force was applied axially with enough force to cause the center of the 12" span to bow outwards, off axis a 1/4", the member would also shorten approx .030" (???), and toe would change .030".

I have not checked these actual numbers yet, just a rough guess from what I calculated in a past thread. But the point is still valid, our sleeves are not bowing a 1/4", and if they were, they would soon fatigue and fail, and they aren't and .030" ain't that much anyway.
