Batch-yield calculation method
The initial sample mass is multiplied by its THCa mass fraction to determine the THCa available. Applying the 0.87723 conversion factor gives the theoretical THC mass. The difference is CO2 released, which is subtracted from the original batch weight.
Other components are modeled as mass-stable. Real samples can lose water, solvent, terpenes, and other volatiles, and existing THC must be accounted for separately.
Questions & limitations 2 answers
Is the final batch weight the same as the THC yield?
No. Final batch weight includes other material assumed to remain in the sample. THC yield is only the mass of THC formed from the initial THCa fraction.
Does the yield calculation account for processing losses?
No. The model assumes complete conversion and treats all non-THCa material as unchanged. Evaporation, transfer loss, degradation, and residual solvents require separate accounting.
