@helpful-application-7107 I never deleted the metrics, so it was the same metrics - as in going to the metrics overview - but the underlying query (from fact tables) is different. I did however think that I would need to recreate them, but I guess that's the beauty of fact tables hehe.
The primary thing I did in the fact tables was to change the identificator and create a join table instead. And actually writing this message I realize that it might be there the issue is? That the power calculator perhaps doesn't consider join tables, meaning that the metrics need to have the same identificator as the experiment assignment table. Just a thought
