Slinging Rocks!

First, I think it's worth distinguishing between two similar throws: the Figure 8 and the Comanche style.
The main difference is that the Comanche style is a specialized horizontal-lateral variation (modification) of the classic Figure 8 style. "Figure 8" is the general name for a family of throws in which the sling describes a loop in the air in the shape of an infinity sign. The Comanche style takes this biomechanical basis but radically alters the plane of rotation and body position.
The difference between them is determined by three main factors: 1. Plane of Rotation (Tilt) Classic "Figure 8": Performed in a strictly vertical plane (overhand). The sling moves downwards along the body, reminiscent of a baseball pitcher's arm or a tennis serve. Comanche Style: Performed in a diagonal-horizontal plane (sidearm). The "figure 8" leans heavily to the side. The spin and final release are from the side, parallel to the ground or at a slight angle to it. 2. Stance and Body Position Classic "Figure 8": Requires a half-turn of the body. At the moment of the throw, the thrower steps forward (as when throwing a spear), actively engaging the vertical lean of the body. Comanche Style: The thrower stands directly facing the target (frontal stance). All energy is transferred through a powerful twist of the hips and body around the axis (left to right and back again), rather than by leaning forward. 3. Combat and Tactical Purpose Classic "Figure 8": Ideal for shooting from behind cover, from trenches, or in close formation, as the vertical swing requires no lateral space. Provides excellent vertical accuracy. Comanche Style: Developed for mounted warriors and hunters of the Great Plains. The side swing allows for easy throwing walking, running, or sitting, without hitting the horse's rump. It provides a wider horizontal strike zone.
And it seems to me that one of the key aspects of throwing is the position of the elbow, which determines the sling's trajectory. A misalignment of the elbow completely ruins the aim. In each of these styles, the elbow serves opposite purposes.
1. Classic Figure 8 (Vertical Style) In the vertical Figure 8, the elbow acts as a directional vector and should move strictly in a straight line. Correct Position: The elbow is high above the shoulder (as in a tennis serve) and moves straight forward in a vertical plane, aimed at the target. In the final phase of the throw, the elbow "leads"—it moves ahead of the hand, pulling the entire arm with it. Impact on Accuracy: If the elbow is strictly vertical, the shot will never go left or right. Release errors can only move the stone vertically (higher/lower), which is much easier to correct. Typical Error: Elbow "flipping" to the side. If the elbow goes right or left during the final thrust, the vertical plane is broken, and the shot will fly unpredictably to the side. 2. Comanche Style (Side/Diagonal Style) In the Comanche style, the elbow acts as the axis of rotation and should be firmly locked relative to the body. Correct Position: The elbow is lower (approximately at or slightly above ribcage level) and at a fixed distance from the body. It moves in an arc parallel to the ground due to the rotation of the body. Effect on Accuracy: The elbow maintains a tight radius of the throw. Since the throw is from the side, accuracy depends on the synchronization of the body rotation and the opening of the arm. A tucked and controlled elbow ensures that the sling describes a perfect horizontal arc. Typical Error: A "wandering" elbow or one that is too far away from the body. If the elbow begins to extend or rise erratically during the side swing, the radius of rotation constantly changes. The brain doesn't have time to calculate the release point, and the stones fly in a wide horizontal arc (the throw can spread several meters left and right).
