It looks like there are a few different ways to mount the spring (peg, something with screws, shaft collar?). Has anyone tested the shaft collar?

I remember reading that spring manufacturing tolerance is +/- 10% for the k value. Is there some math that determines how this affects the "bendiness" of a spring? How would one even measure the "bendiness" of a spring?
The field drawing specifically calls out a 1/4" long rod (like 0.625 OD or something) that the spring very snugly fits over. The tour video shows a shaft collar not called out in the drawings. I asked about the shaft collar in my question on frc q&a
