There is a difference for a Titan between inflated and deflated.
This is, according to my understanding, to a large extent driven by the "accordion" effect as LS mentions above.
Ad Dr. Eid told me, a perfeclty sized Titan will have some kinks when deflated and no kinks (but with cylinder tips far out in the glans) when inflated.
This means that when a Titan is inflated, it straightens and stretches the tissue of the penis to extend together with the cylinder. This is why cycling makes sense. To keep the tissue flexible enough to allow this to happen.
But, even a Titan cylinder does extend some when inflated. A study measured this to 3-4% or about 0.75 cm for a 22 cm Titan.
The same study also measured hardness, in this study defined as which load required to kink the cylinders of LGX and Titan respectively.
At lower PSI, Titan withstood 2.5 higher force before it kinked.
At higher PSI, the difference was 1.4 times higher.
Study:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5654325/There was also a large study showing huge effects of cycling Titans. Length increase over 2 years was massive.
So there seems to be reason to cycle a Titan.
In fact, the studies I have found on the subject does NOT show any significant difference between the length gain after 1-2 years between Titan and LGX.
The length expanding feature of an LGX is mainly giving the benefit of larger difference between flaccid and erect state. Length gain seems to be equal between LGX and Titan.
In my case, I have gained >2 cm length from immediately post op and 1 cm from pre-op. With a Titan. My difference between flaccid and inflated is 2-2.5 cm.
