And it's pretty impressive based on what Kyle Hill says from about the 8 minute mark onward:
So, yeah, going both via scaling from Kara (who has also done things like lift a submarine out of the water and flew the Fort Roz prison into space etc.) and some of his own feats, CW Superman is already not too shabby. Because he's also got a couple of decent speed and durability feats as well.
