A demo worked once. What should the next batch repeat?

List the components: customer situation, opening, product action, proof and destination. Decide which component the result gives you a reason to investigate. Repeat that idea with enough consistency to learn, while using truthful, appropriate creative rather than blindly duplicating every asset.

Keep the follow-up batch bounded. If the result does not repeat, inspect the differences and the uncertainty instead of inventing an algorithm story. One successful post is a lead for the next experiment, not a permanent production rule.
