How scoring works
The same GearScore engine the comparison pages use. This is the default weighting; open the full comparison to re-weight it around your trip.
GearScore blends published specs into one 0 to 100 number. Livable space per person is a "good enough" gate; weight per person and peak height score on a sliding scale. Price and doors are levers presets turn on.
Customize on the full comparison →- Sufficiency
- Only needs to be good enough. Livable space per person works this way: clear the target and you're set, extra room adds no points.
- Monotonic
- More (or less) is always better. Lighter per person beats heavier and a taller peak beats a shorter one, so they score on a sliding scale.
- Preference
- Type, wall, and pitch are personal preference, never scored. They only filter the list.
