TTDNA ratings
TTDNA ratings are normalized comparison values, not laboratory measurements. They are built from published specifications, technical sources and structured product evidence, converted to one 0–100 scale. Where a directly comparable measurement is unavailable, the value is an evidence-based estimate. Overall-style scores are composites of several characteristics. Methodology

Variants and configurations
6 variantsColour, thickness and configuration are variants of one model — never separate products. Colour never changes a rating, MAX and OX stay qualitative labels, and OX carries no sponge hardness.
