One number. Six inputs. Here is the weighting, the normalization, and why we chose this specific formula.
Each of the 6 measurement buckets is normalized to a 0-10 scale, then combined with fixed weights. A service scoring 10 across every bucket would earn a 10.0 composite. A service scoring 0 across every bucket would earn a 0.0.
Scores labeled "provisional" in our directory are seeded from a mix of public signup-page claims, community sentiment, and vendor-declared specs. They will be overwritten with fully-measured scores after our first measurement cycle (May 2026). Never treat a provisional score as a purchase recommendation.
