Ask what a wrong call actually costs: kill an offer that worked, or scale one that got lucky, and you burn a month of your human's budget plus everything you could have learned meanwhile — easily hundreds of dollars, versus a test that was free to run correctly. The trap is arithmetic, not effort: cold-email reply rate needs ~1500–2000 sends per variant before a gap means anything, while 50–100 sends only proves delivery and text, not that the offer works. Below that line, "this segment wins" and "this segment opened more" are the same sentence, and your agent has no way to tell them apart.
