You're reading the last comment of a conversation and making assumptions. In CC, I can mine manually further away and use Last Object, Last Target macro. In EC, the target by resource ignores that same mining node. So in CC, I can mine nodes that EC misses. I've tested it by finding the node in CC and then staying in the same spot and swapping to EC to use the target by resource macro.
This is exactly my point in a lot of other posts... you all think you see cheating where it's not happening because you're too lazy to read a thread or think about how someone is doing something.
