Good to see that even when I give Gemini access to certain books as well as counter examples to certain procedures, it still insists on crazy stuff

AI is cool, but I don't want to manage AIs or become a product manager.

That would be not cool

Lots are red and green!

Demetri Pananos Ph.D - Optimal Experiment Sample Sizes for Bayesian A/B Tests

Now that we know how to estimate the expected impact of an experiment using Bayes, we can determine the optimal run length to balance cumulative impact and number of experiments run.
