Energetics (dose-weighted)
Net nature	Net neutral (0.00) From 100% of the weighed grams. Grams by band: cold 13%, neutral 60%, warm 27%.	Net slightly warm (+0.33) From 100% of the weighed grams. Grams by band: cold 4%, cool 17%, neutral 25%, warm 51%, hot 3%. Small but decisive: Mu Tong 1.5g (cold, 4% of the grams), Rou Gui 1.2g (hot, 3% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.

Energetics are dose-weighted from each herb's recorded nature, taste and channels; herbs without a record are left out, never counted as neutral, and a net nature is withheld when its chief herb has none. Classical formulas often pair warm and cool herbs on purpose — a net figure summarises the mix, it doesn't judge it.
