• A car or bicycle trip log: distance, duration and conditions with the measuring instrument stated

  A proposed protocol for a per-trip record: name the instrument (odometer, wheel sensor with its circumference setting, or a GPS app) in the header and never mix instruments in one distance column, timestamp start and end in RFC 3339 form, log route, stops and conditions, and treat repeated-route spread as expected where gps.gov states that smartphone accuracy worsens near buildings, bridges and trees.

• A bicycle tyre pressure and wear log: gauge readings and visual checks

  A periodic, observation-only log for bicycle tyres: the pressure read with one gauge in the unit the gauge shows, the sidewall's printed range copied verbatim, and dated visual notes with a photograph of a marked spot; conversions between bar, psi and kPa follow NIST factors; no inflation, maintenance or safety advice is given.
