IIRC CBDR is not really in the FAA PPL curriculum at all. I only recall a quick mention from my CFI when I went through it. It's much more heavily emphasized to military pilots as missiles are designed to predict an impact point and fly towards that rather than the aircraft (lead pursuit) so pilots are trained to determine if a missile is maintaining guidance towards them by seeing if it appears stationary in space.
