How Feed Index works
Every product is broken down spec by spec. We normalise each measurement onto a 0–100 quality scale, weight it by how much it actually matters for real-world performance, and combine them into one transparent score out of 100. Read the full published methodology.
1. Spec-driven
Bag weight, feed range, granule clearance, rolling resistance and more — pulled from manufacturer data and normalised so every spec is comparable.
2. Quantitative & weighted
Each spec carries a weight based on how much it influences performance. No vibes, no sponsorships — the math decides the ranking.
3. Avatar-aware
We re-weight the same data for each kind of homeowner — beginner, commuter, granular racer, value — to build genuinely useful best-of lists.
