The down swing from Ready Position
The backswing of the racquet from ready position is the movement of the racquet from in front of the body to the back scratch position. This term of back scratch for lack of a better name or explanation is the position of the racquet at low point of backswing. The racquet travels down past the toes like pendulum dropping and continuing up until both the right and left are make the letter V and then the racquet drops down the back to the low point of the backswing. This movement is a half circle with a full circle behind the back and another half circle when following through.
