This week we break down "proof coverage," the ratio between how long a product takes to show results and how much of that window a customer's first order actually covers, arguing that selling a 30-day supply of a product that needs 90 days to work quietly manufactures churn and disbelievers. We lay out three fixes, a starter pack framed as "complete the 90-day routine," subscription positioned as continuation after proof, and an honestly labeled single unit, plus a five-move operator playbook for measuring and closing the gap.
