Because while remaining fully loaded and stationary will NOT wear out a magazine spring, it WILL cause it to take a permanent set. (You can see this in large capacity AR and AK magazines.) If you download regularly loaded magazines by one round you'll have a stronger magazine spring to work with when you need it.
Don't agree? Fine! Do whatever you like. I'm not the one who's going to be standing behind your gun.
You clearly have no formal education in metallurgy, material science, or even, mechanical engineering. Spring set is complete nonsense.
