On a few of my bolt mods I have segregated out, in thirds, what I guessed were the "most-used" then "least-used" springs and then the others.
I put them back opposite, more or less, ensuring that Enter, Spacebar, Delete, etc, got the freshest springs.
A couple of times, some mistake forced me to take the whole thing apart again and I lost the fruits of my efforts on the 2nd iteration.
All-in-all, I am not sure that I have felt much difference. I have a jar of spare springs, so I do visually inspect each one that I use and discard any that look "off" or have visual damage.
