"Evolve designs through player feedback not pure theory Dr. Johnny Potts, whose PhD dissertation is the definitive academic work on disc aerodynamics, acknowledges that disc golf equipment has not been engineered top-down from aerospace principles but rather evolved iteratively: designers tweak a disc, "send it out to all their players within their sponsorship team," ask "do you like it, how does this feel," and then "analyze what it actually does on the fairway" to feed that learning back into the next design. This iterative, feedback-driven loop — prototype, deploy to real users, observe real outcomes, refine — consistently outperforms designing in isolation from a purely theoretical model, regardless of the domain.
