In some particular cases, it is very important to tune by yourself. If match circuit don’t complete (in or out ),with RF Circuit. So that Fo (Center Freq.) would be moved in a several MHz from Fo. At this moment, you can tune the screw very carefully , let Fo return to original Fo that you design at the beginning.
