I think it depends on why you are adjusting the driven element. If you are
adjusting the DE because you did not model the feedline or matching system
if used, then there is no reason to change the parasitic elements.

This brings up a big question in my small mind. Assuming you need to correct
element length, I can see you can use SWR to adjust the driven element. But
how do you correctly know how to correct or adjust the reflector, or for that
matter any parasitic element? During the Dark Ages when I first got
licensed,
you just made the reflector around 10% longer then the driven element.
How do
you do it in 2014? (I really don't want to think of remote field strength
measurements while adjusting the parasitic element.) If you correct the
driven
element by 1 inch to lower the SWR, do you then just adjust the reflector by
the same amount?
