Base rating is an estimated baseline from the owner feedback we have available across Amazon reviews and any credible web sources we reviewed. GiftScore editorial signals (build, safety, longevity) are scored independently of that baseline — they reflect what owner feedback and product specs actually say about the product. Some signals are skipped when they don't fit the product type.
