Do I have this right? Maximum absolute, individual guide deflection is 105mm and maximum differential deflection between neighboring guides is 150mm.
If so, I would guess that the highest loads/stresses due to these deflections, on individual straight runs, each with several guides would follow something like this:
Here are seven guides along a straight run and elbows on both ends:
-1-2-3-4-5-6-7-
Let -4- move its maximum = +105mm
To develope the maximum bending, then -3- & -5- would be the maximum opposite or = -45mm
But then what to do with -2- & -6-? I figure a bending reversal would be the worst case. That means these two guides move back to +105mm and likewise -1- & -7- would return to -45mm. I might also confirm that -2- & -6- at -105mm and -1- & -7- at +45mm would not be as large.

Of course all this is highly dependent on what's going on beyond those elbows on either end and the spacing between these guides. I would try to select the stiffest straight run to run this test.
