If you have the ability to adjust VE to make AFR adjustments spot on then
only percieved accuracy of AFR will be relevant and VE accuracy is what you
will be trying to accurately acheive to obtained the AFR input. All depends
on the system being used and the frequency of calibration and accuracy of
your sensor.
