TTDNA ratings
Confidence: medium
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
Sources: Butterfly official product data · Retailer spec listings — weight, sponge hardness and thickness · TTDNA ratings — derived by TableTennisDNA, not manufacturer data
