How scoring works
Every canclusion runs through the same rubric. Five criteria, integer sub-scores from 0 to 10, weighted into a single decimal overall.
The criteria
Each criterion is judged independently on a 0–10 integer scale. Anchors describe what each level means.
Containment
25%How much of the crush stays within the can's original top footprint.
- 10Crush is fully within the original circular footprint. No spread.
- 7-9Minor spread, less than ~20% beyond original diameter on any side.
- 4-6Moderate spread, 20–40% beyond original.
- 1-3Major spread, torn or splayed metal well beyond original.
- 0Crush is wider than tall — flattened sideways rather than down.
Seal
20%Whether the crush closed the can's mouth and drinking aperture.
- 10Mouth fully closed; no opening visible.
- 7-9Mostly closed; small gap or pinhole visible.
- 4-6Partial closure; opening reduced but clearly present.
- 1-3Mouth largely open.
- 0Mouth fully open; no compression at the top.
Symmetry
20%Evenness of the crush around the can's central vertical axis.
- 10Radially symmetric; halves mirror each other.
- 7-9Mostly symmetric; minor lopsidedness.
- 4-6Visible asymmetry; one side notably more crushed than the other.
- 1-3Strongly asymmetric or leaning hard to one side.
- 0Crumpled chaotically with no discernible axis.
Flatness
20%How thoroughly the can has been compressed downward, evaluated against the practical limit of compression while keeping the cylinder contained. A pancake achieved by splaying outward is not flatness — that's a containment failure scored elsewhere.
- 10Compressed to the contained limit. A thin band of preserved sidewall remains visible — that's the optimum for a clean crush, not pancake-flat.
- 7-9Heavily compressed; clearly worked; modest room to compress further without breaking containment.
- 4-6Moderately compressed; meaningful work done but more compression was achievable within containment.
- 1-3Lightly crushed; most original height remains.
- 0No meaningful compression.
Aesthetic
15%Overall craft and visual pleasingness — the model's judgment.
- 10Beautiful, intentional, satisfying form.
- 7-9Nice looking; minor blemishes.
- 4-6Unremarkable.
- 1-3Ugly, jagged, or sloppy.
- 0Mangled beyond aesthetic merit.
The math
Your overall is a weighted average of the sub-scores, rounded to one decimal place (half-up). The same photo always produces the same score: we cache by the image's pixel hash, scoped to your account or session.
Verdicts
- Cancluded. The model is confident in the read.
- Low confidence. The model attempted a score but the photo's borderline. Cleaner lighting or framing will get you a tighter read. (Triggered when confidence falls below 0.6.)
- Inconclusive. The photo isn't scoreable — wrong angle, no can detected, multiple cans, blur, or obstruction. Try another shot.
What we don't do
- We never alter score integrity by tier — free and paid get the same canonical score.
- We never train models on your images.
- We never paywall historical canclusions.
