That being said, I'm not sure how the logic of under exposing and over developing can bring out shadow details can be consistent. There would be less density in the shadows in that case.
Actually, it isn't difficult at all. Just slow down your agitation to something like every three or five minutes, and that takes care of not blocking up your highlights. It isn't perfect, but it sure gives me better negatives then if I just extended the developing time.
