What the score bands mean
Score bands80+ strong60–79 solidBelow 60 limited fit
- 80+: strong marks on the heaviest dimensions with few weak lines in the listed specs.
- 60–79: competitive on most scored inputs, with at least one clearly weaker dimension.
- Below 60: trails this field on the inputs weighted most; the product cards list exactly where.
Source hierarchy
Published manufacturer specifications rank first, dated retailer records second; marketing claims without a checkable figure are excluded from scoring. Missing values never earn invented numbers; they are labeled “not listed - neutral 50” and take the neutral 50 grade the weight definitions describe.
