What we're still learning · 2 data gaps
Good decisions start with knowing what is — and isn't — in the evidence.
- Odor intensity 80 is an archive normalization of AromaWeb's categorical 'Strong' aroma-strength band rather than a source-native 0-100 measurement.
- No public source reviewed in this pass published a directly measured volatility rate or tenacity range for the China-origin lot.
