The weights

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.

Missing values never earn invented numbers; they are labeled “not listed - neutral 50” and take the neutral 50 grade the weight definitions describe.
