Yes, I am a darts dweeb. I dry shoot and look at myself when I ride the elevators in my apartment building. The elevators in the highrise apartment building in which I live have polished metal walls and doors which allow me to look at myself from all angles as I pretend to shoot darts. Naturally, I only do this if no one else is in the elevator. The doormen who sit at the front counter in my lobby monitoring the live video feeds must think I'm some sort of nutcase as I do this day after day. Short of videoing myself, this is the best way to see myself as I pretend to stroke a dart. In the elevator I can see my set up, the height of my elbow, my follow through, the angle of my head, the angle of my shoulders, and the angle of my arm relative to my body. It's very easy to see if I have truly isolated my arm movement from the rest of my body. I can see myself go through a stroke and see how immobile my head, shoulders and body are.
