Energetics dose-weighted
The formula's overall nature, taste balance and channel reach, weighted by each herb's dose. Classical formulas often pair warm and cool herbs on purpose, so a net figure summarises the mix — it doesn't describe every herb in it.

Grams by band: cool 33%, warm 67%.

From 100% of the weighed grams.
Channels reached
