is needed to strike the ball on the center of the clubface.

When the ball is struck on the heel of the clubface, divots tend to be very shallow, if they exist at all, indicating that the downswing had too much out and not enough downward force.

When the ball is struck on the toe of the clubface, divots tend to be too deep. This indicates that the downswing forces had too much downward and not enough outward force. This is your situation.

I would think that actively driving and directing the sweet spot of the clubhead with pressure point 3, the trigger finger, OUTWARD towards the inside quadrant of the ball will cure this.

I would give "heelers" similar advice, except I would change the last part of the sentence to read "DOWNWARD" towards the inside quadrant of the ball.
