What is the primary authority in teaching a golf lesson, according to the provided information?

The primary authority in teaching a golf lesson is grounded in the context that technology plays a crucial role in providing objective data and insights that can enhance a golfer's understanding and improvement. Utilizing technology, such as swing analysis software, launch monitors, and video playback, gives instructors the ability to assess a player's technique with precision. This allows for tailored instruction based on measurable performance metrics rather than solely relying on subjective observations.

While aspects like ball flight, player feedback, and an instructor's experience are certainly important in the teaching process, they can often be influenced by personal biases or variability. Technology offers concrete evidence that can lead to more accurate diagnoses of a player's strengths and weaknesses, making it a central pillar in modern golf instruction. Therefore, technology stands out as the primary authority, serving as a foundational tool that supports all other teaching methods.
