How does zener impedance affect the voltage?

The dynamic impedance of a Zener causes a change in the Zener voltage with current (when above the breakdown voltage). It's thus determines the accuracy of the voltage with change in current. If the Zener current doesn't change in operation, than the Zener impedance is not critical.
