I tried this throughout a couple of positions of CV joint extension with relation to the axle.

This sounds like a good test to me. Of course it should not be clicking when driven. My 928 developed a click that I noticed a low speed while backing into my driveway. The boots looked good, but one end of one was a bit loose and water poured out when I took the boot off. Even though there was plenty of grease still in there all the components were rusty. The other CV joint on the same half-shaft looked fine, but when I cleaned it to repack it with grease I found a gouge in the inner race that looked like a manufacturing defect that had been uncovered as the joint wore. Had to change both joints.
