How Datum Grade 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
Receiver weight, hardware range, cartridge 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 shooter — beginner, commuter, competition racer, value — to build genuinely useful best-of lists.
