LLMs can make mistakes. Check important info.

It seems like you're trying to share benchmark results and code snippets from a test case, but the format is not suitable for this platform.

However, I can try to help you extract relevant information from the shared data:

1. The `Html Preparation Code` section appears to be unnecessary and can be ignored.
2. The `Individual test cases` section describes two benchmark tests:
	* "Ramda.mergeDeepRight" with a description of the benchmark definition as "R.mergeDeepRight(obj1, obj2)".
	* "Lodash.merge" with a description of the benchmark definition as "_.merge(obj1, obj2)".
3. The `Latest benchmark result` section shows two benchmark results:
	* For "Ramda.mergeDeepRight", the raw UA string is from Chrome 95 on Mac OS X 10.15.7, and the executions per second are approximately 26,572.
	* For "Lodash.merge", the raw UA string is also from Chrome 95 on Mac OS X 10.15.7, but the executions per second are much higher, at approximately 33,820.

If you'd like to ask a specific question about these benchmark results or need further assistance, feel free to ask!
