In my experience downswing blackout is the loss of clubhead awareness. Or better described as loss of lag pressure which is felt in the pressure points of the hands.

Agreed, lag is the glue that ties everything.
Lag is easilly felt through PPT#3 and I also closely monitor it tracing the base of the plane line to ensure I direct my thrust on the right track.

It keeps me focused on REPRODUCING the FEEL, shot after shot, rather than thinking about my technique.

Sometimes I also end up replacing tracing by the aiming point technique if I need to alter the ball's flight.

So, it is: "Mind in the hands" where Lag is felt and direct hands/lag along the right path.
