You're fighting the battle of the sustained tension vs cycle number. Your spring will go through more cycles if you release and recock after every opening instead of just leaving it cocked, which could wear out your spring faster. I doubt the spring force is enough to permanently deform the spring by letting it stay cocked.

Coil springs can go through almost endless cycles though.

For me, leave the leaves cocked, relieve a coil.
