I've been using the GDS for two seasons now. For the strike (swinging or called), I rise out of the stance and face F1 while I point down the 1st base line for RHB's. For LHB's, I just use a slight turn to point down to 3rd base. For the called strike three, I push my right arm out in front of me, palm & fingers open. As I rise, I extend the left arm out to meet the right, close the right fist and "pull the bow" back as I transfer my weight (all 255 lbs) back on my right leg.
It actually took my wife to get the step by step down on the strike three call. I never realized how involved a simple thing like that was. Well, after almost 30 years of "perfection".........
