It feels like I’m stuck at the same tension with mine and not gaining anything.
Gekiro, the effects of stress relaxation (the mechanism), or more accurately static progressive stretch (the method), have been shown to have a very efficient ability to elongate connective tissue permanently. More efficiently than creep-based traction, in fact. So I do think it would work slightly better as an extender design.
There is one important note: whether screw-based or spring-based, an extender is still an extender. Whichever method you use, you should expect to have to spend significant time in your extender. So while a spring-based extender might take 1000-2000 total hours to gain an inch, I wouldn’t expect the same results from a screw-based extender in 500 hours. Either method is all about maximizing time.
