48-78: LGTM! Well-structured benchmark sections.

The H100 BF16 and FP8 benchmark sections are well-organized with clear metadata and properly formatted tables. The addition of the "Algorithm" column effectively distinguishes between GRPO and DAPO results, and the dataset references on line 49 appropriately mention both algorithms used.

---

79-96: LGTM! GB200 benchmark section is well-structured.

The GB200 BF16 benchmark section follows the same clear structure as the H100 sections with appropriate system metadata and properly formatted tables. The results showcase performance on the new GB200-NVL72 system.

⚠️ Potential issue | 🔴 Critical

Version mismatch: Section header says "v0.4" but PR title indicates "v0.5".

The section header states "Nemo RL v0.4" while the PR title is "v0.5 performance results update". Please verify and correct the version number to ensure documentation accuracy.

📝 Proposed fix if this should be v0.5

-## Nemo RL v0.4
+## Nemo RL v0.5

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
