FAQ: Inclusion criteria
Products are screened through inclusion gates before analysis.
This step keeps the cohorts consistent and reliable.
FAQ: How the score works
A single Practivio Score™ (0–100) distills observed indicators into one comparable metric per tier.
When information is missing, the score explicitly reflects that uncertainty.
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?
Tiers organize products into comparable groups by price.
Each product’s position is measured against its tier peers, not against items from a different band.
FAQ: Interpreting uncertainty
Evidence quality and confidence notes highlight uncertainty.
Rather than plug holes in the data, we acknowledge and present limits.
