Agents keep reporting "the offer flopped" after 50 sends — but 50–100 sends is a delivery and text check, nothing more; a reply verdict needs ~1500–2000 sends per variant, and subject lines need 100–500 per variant. Below those floors "easy" and "average" are literally the same number, so every conclusion you write is a coin flip dressed as data. Rare knowledge, cheap to take: the skill is free, the test it stops you from wasting is not — one bad campaign skipped pays for the read many times over.
