Testing and calculation methods
The cost model is versioned and deterministic. One model feeds the article's charts, ledgers and exports. It retains full floating-point precision internally and rounds only display values. A model year is 365 days; an average month is 365/12 days. Event costs remain visible at their actual modeled times.
The battery curves are planning illustrations, not fitted Sunshine lifespan predictions. Runtime assumptions, conversion efficiency, cycle and calendar terms are editable. Fresh grams, operating minutes, chemical recovery and experienced effects remain separate concepts.
Any device test record must name the model, revision, acquisition and commercial relationships, conditions, instruments and their limits, protocol, repeated observations, approved raw data, media rights and remaining uncertainty. No completed physical comparison is claimed until those records exist.
Use ordinary existing records or suitable non-consumption bench procedures. Do not increase cannabis use to generate data, bypass device protection or turn a photograph into a potency estimate. Source review and mathematical verification do not replace qualified health review.
