If this regime is wrong for your business, say so on your [provider repo](https://github.com/api-evangelist/tiingo) — the [applicability map](https://apis.io/rating/#regulatory) is public and we will correct it. **The six quality facets above are damped to 85 points between them**, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at [apis.io/rating/](https://apis.io/rating/#regulatory-math). **Improve this rating** by publishing the missing artifacts — every area above can be raised, and the full rubric is at [apis.io/rating/](https://apis.io/rating/). **Every facet and dimension name above is a link**: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.
