When successfully validating a pull request, there is a "view details" link under the "Merge and validation checks" section. When clicked, in the new page that opens there is a button "Export test results…" that allows me to download the test results in excel file with detailed precision, reporting each test method duration.

Unfortunately this feature is only accessible when PR are being validated, and disappears when checking historic PRs already closed and deployed. Would it be possible to provide such data?
