At the moment the only information on a tube of shuttles is the speed and there is no recognized standard for this. In a sport where the characteristics of the projectile is fundamental this is ridiculous.
We at Bird Design are working on some simple tests to set a standard. Weight and size are already defined. Final spin rate and rate of spin acceleration need to be defined. Porosity of the skirt is easy to measure. Rigidity of the skirt is easy to measure. Grip on the racket face can be measured. Flight parabola (peak and drop) is less easy to measure but is a function of the value of all the other attributes.
Any inputs to this work would be welcomed.
