How it works
This is my 4-day method, turned into a schedule you can follow. When I launch a product I treat the first few days like a street fight: test cheap, feed winners, kill losers fast. The budgets escalate because a proven winner deserves more fuel, not because bigger is braver.
The whole logic, the 5-5-5 testing formula, the kill rules, the duplication counts, lives in the 4-day scaling playbook. This planner just does the budget math so you can see the ramp before you commit.
Cash flow will kill you before bad ads do. Those Day 3 numbers get big, and your payout holds do not. Make sure you can float the spend before you scale into it, see the cash-flow playbook.
