And you never will.
"PROPERLY" designed/manufactured springs do NOT "take a set" and do NOT need a "rest". They can only lose "power" (the ability to return to their designed shape/position) by means of cycling.
The one exception is when/if a spring is compressed or stretched beyond its design limit (modulus of elasticity), then.... permanent damage is done.
The only good reason to "rotate" a magazine.. is to occasionally clean and inspect it for damage, the spring itself (if properly manufactured) should be fine.
