I was surprised about Ching knowing they have Kryptonian organelles, how could he tell?
Ooh! Good point.
In the comic books (in at least 1 story line) the SCU studied Superman's patterns and could fairly well predict when and where he would intervene. That way they could schedule extra people for his 'off' hours and have plans for how to work when he did show up. But Superman wasn't great on showing up for planning meetings.
