Ignoring the default setting of numeric parameters

I have an OpenAPI spec with the following parameter:

- in: query
  name: limit
    type: number
    default: 3
    description: Number of results to return. Always default to 3 unless specified
              with an exact amount by the user.
  required: false

I then use a prompt of the form “Show me some [resource I’m requesting]”. ChatGPT then consistently uses 5 as the limit parameter instead of 3.

Is there anything else I could do to the spec to help encourage ChatGPT to help encourage the model to start with the defaults we set? Happy to create a minimal repo if my issue as stated is unclear.
