Should You Always Be A.B. Testing When You Release Any Features?

CAC: I would say the question was should you always be A.B. testing or is it a qualitative data that you can use to infer how a product or feature is doing? CAC: If nothing happens and there's no change you really don't know why. So just peace of mind really. When you showed it when you showed it right. And the last thing I would say is be considerate. Be considerate about the things that I discussed a little bit earlier about optimizing for statistical versus practical significance.
