Ran my first A/B test on a $19 ad and the 'loser' version drove 3x the signups

I was so sure the cleaner headline would win that I almost killed the ugly one early, but a guy on a marketing Discord begged me to let it run the full 7 days in Chicago. Turns out the weird, typo-looking one pulled 42 clicks and 9 email signups, so now I'm wondering what else I've been stopping too soon, anyone got a rule for how long to let a test ride?
