+## Summary Histograms
+
+The histograms below show the distribution of performance changes across different .NET configurations, categorized by the magnitude of change. Each chart displays:
+
+- **Valid Regressions**: Performance decreases that have been confirmed and linked to specific commits
+- **Noisy Regressions**: Performance decreases that were detected but marked as potentially unreliable due to measurement noise
+- **Improvements**: Performance increases (includes both valid improvements and noisy measurements, as these have not been individually validated)
+
+**Important considerations when interpreting this data:**
+
+1. **Test coverage varies by feature**: Different .NET features have different numbers of performance tests. A single code change might appear as 1 regression or as many as 30+ regressions depending on how many tests exercise that particular feature.
+
+2. **Improvements are unvalidated**: Unlike regressions, improvements have not been individually verified, so some may be due to measurement noise rather than actual performance gains.
+
+3. **For detailed analysis**: Review the individual regression and improvement reports linked above to understand the root causes and specific changes responsible for performance impacts.
