TTDNA values are analytical 0–100 scores derived from official specifications, construction and verified category data. They are never official JOOLA ratings and are never shown as manufacturer values.

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

4 variants

Colour, 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.
