Built a small tool using GPT for gaming performance feedback — curious about others' experience

Hey everyone,

I’ve been experimenting with using the API to help analyze user input/performance data for a small side project related to gaming peripherals (mouse sensitivity/DPI testing). It’s been an interesting exercise figuring out how to structure prompts so the model gives consistent, useful feedback rather than generic responses.

A couple of things I’m still figuring out:

  • Best way to keep responses consistent across different input ranges
  • Whether few-shot examples or stricter system prompts work better for this kind of numeric/analytical feedback

Would love to hear if anyone else has built something similar — data-analysis-style tools where the API needs to reason over numeric inputs rather than just chat. Any tips on prompt structure would help a lot.
