Kestrel Drift

Evidence by source type

Each source is weighted by how reliable it is, how much data it has, how recent it is, and whether it shows signs of fakes or sponsorship. Then we shrink toward the category average (62) so thin evidence can't look perfect.

Adjustments

• Unboxed Weekly: paid placement, counted at 35% weight
• Parcel stars: weight cut 75% (only 58% verified purchases, 86% five-star (category norm is ~70%), reviews arrived in bursts, many near-duplicate review texts)

Aspect scores
