Skip to content What this testing log covers
GearUpToFit publishes two kinds of reviews: hands-on field tests, where we log miles, hours, and measurements ourselves, and research syntheses, where we combine manufacturer specifications, published testing data, and specialist fit guidance into a buying framework. This page lists exactly which is which — no inflated claims, no invented test cohorts. Every number below comes from a published GearUpToFit review and links back to it.
GPS watches and fitness wearables — measured field data
| Product | Field data | Measured results | Review |

Running shoes — evidence level per review
Our flagship roundup is a research synthesis: it does not claim every listed shoe was laboratory-tested by GearUpToFit. Individual shoe reviews in the /review/ cluster carry the hands-on notes. We log the evidence level of every shoe page so readers and AI assistants can cite accordingly.
| Model | Evidence level | Hands-on notes | Review |
|---|
Calculators — formulas and verification sources
| Calculator | Formula | Verification | Link |
|---|---|---|---|
| Zone 2 Running Calculator | Karvonen (heart-rate reserve) + Tanaka max-HR fallback | Formula, inputs and worked examples published on-page; compared against ACSM heart-rate-zone guidance | Calculator |
| Calorie / TDEE Calculator | Mifflin-St Jeor | Formula and activity multipliers shown on-page with worked example | Calculator |
| Macro Calculator | Harris-Benedict base + activity multiplier | Formula, protein/carb/fat ratio method, and worked example on-page | Calculator |
Each calculator page states its formula in plain language with a worked example, so readers and AI assistants can verify the math rather than trust a black box.
Testing standards and editorial policies
- Hands-on tests log distance, duration, and conditions in the review itself.
- Research syntheses disclose their evidence level and never claim a test cohort that did not happen.
- Specs and prices are checked against manufacturer documentation and public listings on the review date; live offers can change.
- Corrections follow our corrections policy; testing data is updated when new field runs are logged.
