Build Your Own Equal Game Time Calculator
A 6-lesson course that teaches you how to build a custom GPT that calculates fair playing time rotations for your team. No coding. No tech skills.
The problem
14 players. 7-a-side. 40 minutes. Two want striker. One can only stay for the first half. Your goalkeeper wants outfield time. Every parent is watching the clock.
You could use someone else's tool. Or you could build your own that knows your squad, your format, and your constraints. One that works exactly the way you want it to.
That is what this course teaches you to do.
What you will build
A custom GPT that takes your squad size, match format, duration, and any constraints, and gives you a fair rotation plan in seconds. It handles:
Any format
5-a-side through 11-a-side. Rolling subs or fixed sub windows. Any match duration.
Player constraints
"Jake plays goalkeeper first half." "Mia leaves at half-time." "Three players are carrying knocks."
Positional variety
Rotates positions, not just bodies. Players get development time across the pitch.
6 lessons, one working GPT
What are custom GPTs?
What they are, why they matter for coaches, and how they differ from just chatting with ChatGPT.
Choosing your tool
Why an equal game time calculator is the perfect first build, and how to scope it properly.
Writing the system prompt
The instructions that tell your GPT how to behave. This is where the magic happens.
Adding a knowledge base
Give your GPT specialist knowledge about formations, age groups, and FA guidelines.
Testing and refining
How to test edge cases (late arrivals, goalkeeper rotation, odd squad sizes) and improve your GPT.
Publishing and sharing
Put it on the GPT Store, share it with your coaching team, or keep it private for your club.
Why build your own?
You could just use the free one
There is already a free Equal Game Time Calculator GPT that works out of the box. So why build your own?
Because building it teaches you how custom GPTs work. Once you know that, you can build anything: a session planner that knows your team, a match analysis tool, a parent communication helper. The calculator is the starting point, not the destination.
The skill transfers to everything.
$10 until 26 April
6 lessons. One working GPT. A skill you will use for every tool you build after this. Normally $24.
