Editorial policy

PetMathStudio is written and edited by James Wu. The site publishes calculator-driven research, not hot-take opinion. This page documents the standards every page is held to.

Sourcing

Numbers and claims come from primary references — see /methodology for the tiered source model. Pages cite by name, not by vague phrasing like “experts say.”

Review cadence

Each page lists an “Updated” date. Durable claims (RER and MER formulas, NRC nutrient tables, WSAVA body-condition rubric, AAHA life-stage definitions) are reviewed at least annually against the current published edition. Time-sensitive claims (a pet-food brand's posted kcal/cup, a manufacturer recall list, a vet protocol update) are reviewed when the underlying source updates; pages with that kind of dependency ship a visible refresh cadence at the top.

AI policy

AI tools assist with drafting and editing. Every number, formula, and source citation on this site is human-verified before publish — AI is not trusted to invent specifics. Pages that include any AI-assisted feature (such as the on-site assistant) carry a visible disclosure.

Corrections

If a page has a factual error, email admin@petmathstudio.com. Corrections are made promptly and the page's “Updated” date reflects the change.
