It also depends on what the screen content happens to be... I'd be sure running Horror flicks or Bold and the Beautiful all day for the kids won't give the same outcomes as Sesame Street and Playschool. It's also what are kids missing out on by sitting in the isolated screen environment, not that they feel ok doing so... The point is always simplified for some broad guidance rule while ignoring the required complexity to properly understand and advice on a 'problem.' That and people lie/embellish when interviewed on the phone, so that would have a huge margin of error.
