This product's Amazon sales rank jumped 3× over its own pre-surge baseline. We called it a dud: the data said this spike would fade fast.

Amazon sales rank, inverted — higher = selling better. Dashed line = the day we made the call.

HOW THIS CALL IS GRADED

Every call is graded against the same fixed bar, set before the call is made: three weeks after the surge began, is the product still selling at at least 2× its pre-trend pace AND ranking among its category's proven sellers? Clears both = a keeper call was right. Fails either = a dud call was right. No judgment calls, no moved goalposts. The six-week verdict asks that same question again over days 31–42 instead of 10–21 — nothing is redefined, it is simply asked later, because sourcing takes weeks. This call was posted publicly in real time, before the outcome existed.

Scryup calls Amazon trends — keeper or dud — on day 3, from the data.

Every call is posted publicly and graded in the open at three weeks and again at six, hits and misses both. See the whole board, or check any US product free — paste an ASIN and we'll email you the keeper-or-dud call.
