I can relate to the issue: tests work with specific check conditions, and there might other side effects that are not critical to the test but still impacting the user. For instance a page that properly loads, but surprisingly slowly. If you had no requirement of speed and it still loads within the test timeouts, it will pass fine, but a manual check would have raised the issue and perhaps underlying well hidden bugs.
