FAQ: How the score works
The Practivio Score™ is a 0–100 measure combining multiple observed indicators within a price tier.
If inputs are missing, we don’t substitute—we mark the score as less certain.
FAQ: What “signals” means here
We use the word “signals” to mean the combined observational data used to compare products within a tier.
FAQ: Why price tiers?
Grouping products into price tiers creates consistent, fair evaluations.
Each product’s outcome is tied to its own tier, not to the entire market at once.
FAQ: Interpreting uncertainty
We show uncertainty directly in the evidence base and confidence notes.
If data is sparse, we present outcomes cautiously rather than speculate.
