How Much Time Does It Take to Do an Experiment?

How much more time does it take to do something that we think potentially save us more time in the long run? We're trying to navigate potential debtends early. And probably more importantly, is to come up with the most rigorous designs for at least we learn something at i think what happens a lot is that you see iteration of experiments. Its not not a great design, really small sample size, highly visd, and it's not replicable.
