 ## Introduction
 
-**Confidence scores** were introduced in [v2.34.0](https://github.com/docling-project/docling/releases/tag/v2.34.0) to help users understand how well a conversion performed and guide decisions about post-processing workflows. They are available in the [`confidence`](../../reference/document_converter/#docling.document_converter.ConversionResult.confidence) field of the [`ConversionResult`](../../reference/document_converter/#docling.document_converter.ConversionResult) object returned by the document converter.

 Confidence scores provide a quantitative assessment of document conversion quality. Each confidence report includes a **numerical score** (0.0 to 1.0) measuring conversion accuracy, and a **quality grade** (poor, fair, good, excellent) for quick interpretation.
 
-Use cases for confidence scores include:
+!!! note "Focus on quality grades!"
+
+    Users can and should safely focus on the document-level grade fields — `mean_grade` and `low_grade` — to assess overall conversion quality. Numerical scores are used internally and are for informational purposes only; their computation and weighting may change in the future.
+
+Use cases for confidence grades include:
 
 - Identify documents requiring manual review after the conversion
 - Adjust conversion pipelines to the most appropriate for each document type
 - Set confidence thresholds for unattended batch conversions

 A confidence report contains *scores* and *grades*:
 
-- **Scores**: Numerical values between 0.0 and 1.0, where higher values indicate better conversion quality
-- **Grades**: Categorical quality assessments based on score thresholds:
-  - `POOR`: Score < 0.5
-  - `FAIR`: Score < 0.8  
-  - `GOOD`: Score < 0.9
-  - `EXCELLENT`: Score ≥ 0.9

-- **Page-level**: Individual scores for each page, stored in the `pages` field
