Different approach on the same theme: I go forward of where I want to drop the anchor; set the anchor watch; then drift back and drop the anchor just forward of the spot. This eliminates a lot of the error.
I'm waiting for the real anchor drag alarm system. You will attach a transmitter to your anchor. There will be a receiver hanging off your boat (has to be below the keel). The receiver measures the distances and direction to the transmitter. The receiver takes that information and a GPS position to determine an accurate position of the anchor (transmitter). So instead of monitoring a 200' swing radius of the boat, we keep the anchor in a 25' (to allow for GPS error and anchor reset) radius circle. The transmitter and receiver for underwater use have exited for 20 years already. Someone just needs to build the unit and and the top side box.
