Sorry but this is just wrong, no if's or but's.

Any rudder you hold in will cause you plane to fly through the airmass in an arc if your wings are level. The only exception to this is is the rudder is compensating for a bad engine thrustline or asymetrical drag.

IF you are flying inside wing low like many fliers do, and the Aussie's observations at many F3A WC's suggest, even the top guys do it, then yes you will need to hold rudder out if the wind is blowing in or calm. I've personally seen a current top US pilot flying inside wing low and an arcing baseline and it wasn't by accident as every pass (left and right) was inside wing low with an arcing baseline..
