Yinhe lists hardness either as a Chinese sponge degree or as a named grade. Both are shown exactly as published and are never relabelled Shore A, Shore C or ESN. No reliable official Yinhe list price is published per region, so no price is shown rather than an invented one.
TTDNA ratings
Confidence: High
TTDNA values are TTDNA's own editorially normalised 0–100 ratings. They are never an official Yinhe rating and never a conversion of Yinhe's own speed or spin scale.
