Yeah, I had exactly the same reaction. When I take the time to scan for artifacts, I get close to 100%, but when I try to do it quickly, I get close to 50%.

That 100% will gradually come down as the tech improves. And I'd guess the tech is already good enough that most people won't be able to improve on 50% success at first glance -- I don't think my instinct would noticeably improve with practice.
