Darts on TV

Some dart championship was on fox yesterday. I taped it and watched it. Here are my observations:

• Most grips didn't have thumb (tip) under but to the side. Perhaps my grip is viable
• Some strokes didn't have a draw back? Heck, Hank Arron batted with his left hand on top at one point (not professional).
• Throwing motion was more like a pushing motion than a thow. The motion starting forward had little elbow movement but after the arm reached perpendicular with the floor the elbow was coming up.
• The hand was pointing at the board as the follow through... not moving towards the floor or finishing
• 3 dart ave around 80-100
