Acted on docs/gps-model-findings.md (independent analysis of 156 rides).
Implemented:
- crrFromAccel extended past the old 0.008 ceiling: 7-11 -> 0.008,
11-15 -> 0.012 (packed dirt), >15 -> 0.020 (grass/rut/gravel). Rough
surfaces were undercounted ~3x. Applied to session median and per-point Crr.
- Auto walk-the-bike detection (single-speed only, gear_count 1/unset):
a normal-fix segment slower than the 30-rpm-cadence speed is the rider
pushing, not riding. Excluded from ride distance/speed/elevation (elevRef
reset so a pushed climb doesn't merge with the ridden one); effort counted
as walking, not bike physics. Every sub-threshold point excluded regardless
of duration; only runs >=30s reported as walked (walkBikeSec/walkBikeMeters).
gearCount threaded through every computeStats/finish caller.
Documented as known limitations (left as-is by decision, need calibration/DEM):
- kcal max(physics, MET) never sums the biological overhead, so climbs are
slightly undercounted (comment + README + PROJECT_MAP).
- absolute elevation gain is bounded by the raw GPS altimeter (tens of
percent; needs a terrain model / wired DEM preload).
