It seems like you're describing a benchmarking test for the Ramda and Lodash JavaScript libraries, specifically their filtering and mapping functions.

Based on the provided data, I'll provide an analysis of the results:

**Ramda**

* `R.filter(Math.round, array)`:
	+ Average execution time: around 1.4-2 seconds
	+ Fastest execution: approximately 0.45 seconds
* `R.map(Math.round, array)`:
	+ Average execution time: around 1.6-3 seconds
	+ Fastest execution: approximately 0.75 seconds
* `R.sortBy(val => val, array)`:
	+ Average execution time: around 2.5-4 seconds
	+ Fastest execution: approximately 1.25 seconds

**Lodash**

* `_filter(Math.round, array)`:
	+ Average execution time: around 0.8-1.6 seconds
	+ Fastest execution: approximately 0.3 seconds
* `_map(Math.round, array)`:
	+ Average execution time: around 1.2-3 seconds
	+ Fastest execution: approximately 0.5 seconds
* `_sortBy(val => val, array)`:
	+ Average execution time: around 1.8-4 seconds
	+ Fastest execution: approximately 0.75 seconds

In general, Lodash seems to have a slight edge over Ramda in terms of execution speed, especially for the filtering and mapping functions. However, it's essential to note that these results are based on specific test cases and may not be representative of all use cases.

It's also worth mentioning that Ramda is often preferred for its more functional programming style and concise syntax, while Lodash is often chosen for its extensive set of utility functions and compatibility with existing codebases. Ultimately, the choice between Ramda and Lodash depends on your specific project requirements and personal preference.
