That is correct, sorry that it isn't labeled or anything. 

 Don't superraid for CvC points.

Just quoting for emphasis. It took me a run to realize that too.

Well yeah, while it's a bit unobvious, CvC points are awarded for dungeon completion not for the artifacts you get, and the double energy spent only doubles your rewards, not the number of completions. 

I'm running spider super raids right now. Yes, the CvC rewards are baed on something like "clear the spiders lair."  On a CvC points per energy members of our clan have recommended turning super raids off.

However the dungeon diver's event is running concurrently, which is somehting like "collect artifacts from dungeons" so both artifacts do count here.
