Honestly, 8 ads at $50 a day is just throwing money into a void. Meta can't learn anything useful from $6 per creative - you're basically paying for noise, not data.
Kill all but the two highest CTR ads now. Don't wait until Thursday. Run those two at $25 each and you'll actually get some signal without torching budget on six creatives that can't tell you anything yet.
That $220 on one impression? Classic placement glitch - usually Reels or Audience Network. Check your placement breakdown and cut whichever one that hit on.
Happy to dig into your CTR numbers if you want - I can tell you exactly which two to keep.
