1. The idea

What a coach is doing in the last five minutes

A good coach builds a mental model of each student: where they are today, what they could do better, what to focus on now and what later. It is built from experience, from what worked with other students, and from what the coach sees in that hour. Most of the thinking happens in short gaps during the lesson, and it peaks at the end, when the coach has seen everything the session will show.

That is the moment this business is built around. At the end of the lesson the coach's picture of the player is the most complete it will ever be. From then on it fades, because the next student is already on court. A coach with a good memory keeps some of it; nobody keeps it at the same altitude or the same detail.

What the player is doing in the same five minutes

The player has just been given an hour of instructions. "In your next game, focus on these three things" is hard to remember, harder to follow, and nobody checks. Worse, the lesson and the game are different places. Many players play better in a lesson than in a match, and the match is the point. Nothing that happens in a game reaches the coach.

What goes wrong across lessons

Why this has not been built

Capturing and using this knowledge well needs a lot of iteration: the right questions, the right note, the right view for the player, the right briefing for the coach. In the past that meant an application, engineers and months. Now a voice memo, an assistant and a vault are enough to start, and the iteration that finds the right experience is the cheap part.
