Overview

Sampled 150 users over 30 days longitudinally.

Metric	Value	What it tells us
Total events	2 670	30-day sample size.
Median events / user	16	Half the users log ≤ ~1 scan every other day.
Median duplication ratio	0.50	One-in-two scans is an exact repeat of something they already logged.
Users with dup-ratio > 0.60	4 (9 %)	Extreme repeaters.
Users with dup-ratio < 0.20	4 (9 %)	High-variety “explorers”.
Median semantic similarity	≈ 0.34	Food names per user are moderately alike (lots of variants on the same staples).

Notable segments

Segment	Example ID	Events	Dup-ratio	Semantic sim	Staples
Ultra-repeat power logger	vJd5w8jr…	310	0.65	0.35	27× “Waffle”, 24× “Spaghetti + Beef”, plus pizza & nuggets. Breakfast/dinner on auto-pilot.
Routine breakfasters	Mlmd…4j2 (from earlier run)	55	0.62	0.47	Scrambled eggs, bacon, avocado variants. High semantic overlap → same meal, tiny tweaks.
Protein-and-fruit snackers	Bv8LBjMj…	90	0.50	0.34	Blueberries, protein yogurt/whey, salads—healthy repetitive snacking.
Low-variety low-volume	iarW…TK2	2	0.50	0.00	Logs one frozen meal twice—likely feature test or diet plan.
Explorers / foodies	TA4nY7Vb…	193	0.31	0.37	133 unique foods; repeats mainly “Breakfast Plate” & bananas—otherwise very diverse.
Synonym duplicates (very high semantic sim)	RzbkvID…	4	0.50	0.83	“Steak” vs “Beef Steak” → data normalisation opportunity.
Single-food binge	TVaxCTpn…	4	0.75	0.00	4 scans of “Goldfish Crackers” in a row—temporary craving or barcode test.

50 % literal repetition is the norm. Predictive fill-in or “log again?” prompts should boost UX for the majority.
High semantic similarity but different names (e.g., “Steak” vs “Beef Steak”, “Blueberry” vs “Blueberries”).
Extreme repeaters (> 0.6 dup-ratio) make up ~10 %.
Explorers (< 0.2 dup-ratio) are equally common.

- Generic labels like “Food Plate”, “Breakfast Plate” still frequent.
Most-logged staples across users
- Eggs / breakfast plates
- Bananas & other single fruits
