DELT's Library and the suggestions the app makes are all grounded in verifiable evidence. This page sets out the editorial standards by which that evidence is handled.
1. We rely on primary literature
The methodology DELT presents draws on peer-reviewed exercise-science literature. As a rule, the figures, thresholds, and claims in our articles are accompanied by their source (author and year, and a DOI where available), so that readers can trace them back to the primary information.
2. We do not fabricate data
We do not use mock data, invented cases, or non-existent reviewers to dramatize an effect. Charts and figures are published only when they are backed by real literature or by DELT's own implementation.
3. We do not promise results
We make no unfounded promise that a specific outcome will be achieved within a specific period. The literature speaks in conditions and probabilities; we avoid assertions that ignore individual variation.
4. We distinguish design values from sources
Implementation parameters that DELT defines for product behavior (such as the threshold for stagnation detection) are stated explicitly as values DELT designed, not as academic consensus. We do not let values drawn from the literature be confused with values the product sets.
These standards put evidence and honesty at the foundation of DELT. The individual methodologies are documented in the Library. Corrections and questions are welcome at support@getdelt.com.
