A coaching interface should make the coach feel like they're levitating — receiving insights without cognitive load. The test for every UI element: can the coach parse it in under one second while watching 24 swimmers? Does it use coach vocabulary instead of statistical jargon? Can it be dismissed without action? If any answer is no, redesign. Information-rich effortlessness means surfacing one signal per swimmer by default, with detail available on tap — never fire-hosing data at once.
