Everyone is entitled to their opinion about what traditional archery is, especially since there isn't enough cohesion among archers to give it an acceptable definition for clarity's sake.
For me the only thing traditional about the current olympic archery movement is that a type of bow is used to shoot a type of arrow...and that's about where it ends. It maximizes technology minus cams to shoot sophisticated arrows, bows, sights, and accessories, using target-oriented aiming methods for pounding the same hole over and over again from the same distance, or at least trying to. It is to archery as shooting bench rest rifles is to shooting firearms.
Traditional archery relates to shooting bows and arrows with more self-reliance and less mechanical dependence. It is as much a mindset as it is honing natural hand/eye coordination to shoot and one's woodsmanship skills to hunt, and it has nothing at all to do with 'winning'... unless one sees winning as overcoming the challenges presented by using the simpler equipment and techniques.
Arguments will ensue I'm sure. But to me that's the key difference.
