FAQ: Inclusion criteria

Only products that pass our baseline filters are included.
That keeps every designation valid and meaningful.

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

Signals represent the evidence base — observations about each product — used to anchor it within its peer group.

FAQ: Why price tiers?

Tiers group products with broadly similar constraints so comparisons remain fair and consistent.
A product’s standing is always expressed relative to its tier peers, not across unrelated price bands.

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.
