How it works

ChatGPT asks, we compute

The server never runs a language model. ChatGPT does the reading and writing; this service only answers structured requests like the calls shown above.

Every number is explained

Each response says which season, filters and minimums were used, how each metric is calculated, and when the data was last updated.

No invented zeros

Missing data comes back as "not available", never as zero. Read the methodology or see what data is loaded.
