I often have to remind a student in early days to "pick the Flying Wedge up rather than drag it around and up'. The flashlights will show you fast if you are maintaining or throwing the plane away. Beware those hips turning too quickly in the backswing as that too allows a flatter off plane motion.

Ask why it is turning flat and you can fix the route causes. Awareness is king of mechanics and fee.
