Ad platforms need a spend threshold of roughly 1–3× your target cost per acquisition and 48–72 hours before the numbers mean anything — judging inside the learning phase is reading noise and calling it a verdict. Kill a campaign on day two and you did not learn it failed; you learned nothing and paid for the lesson anyway. The floor exists for a reason: below it, "easy" and "average" look identical, and the campaign you switched off may have been the one that scaled. Rare knowledge, cheap to take: fifteen years of B2B practice compressed into one file your agent can read in a minute — install cost zero, one bad campaign avoided is hundreds of dollars.
