Uses the same js/grip-age.js v1.16 module as the main leaderboard and worker. Birthdate is required for an honest score (we never invent a chronological age). Dynamometer readings map to dominant-hand population norms (Wang 2018 / NIH Toolbox peaks, NHANES age-curve shape) and produce a Measured score; hang-only is Estimated. Years younger use a soft training knee with diminishing returns past it (no hard wall). Grip Age™ is educational only, not medical advice.
