FAQ: Inclusion criteria
Our baseline filters remove non-comparable items.
That makes tier labels clear and defensible.
FAQ: How the score works
The Practivio Score™ (0–100) integrates observed indicators across several dimensions, tier by tier.
Unavailable data points increase uncertainty rather than being guessed.
FAQ: What “signals” means here
The term “signals” covers all the measurable indicators that guide where a product lands in the tier structure.
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
We capture uncertainty through documented evidence and confidence commentary.
Where data is missing, our approach is conservative, not assumptive.
