Reasoning
Treat each source as one perspective. For sources with multiple values, select the most credible representative (e.g., highest confidence or highest-confidence value when ties). The per-source opinions are: Gartner 0; PCMag 1; SalesRobot 1; Trustpilot 60; Nutshell Customers 1; SoftwareAdvice 23. Weights are the average confidence per source: Gartner 1.00; PCMag ~0.75; SalesRobot ~0.70; Trustpilot ~0.867; Nutshell 0.65; SoftwareAdvice ~0.86. Weighted average ≈ (0*1.00 + 1*0.75 + 1*0.70 + 60*0.867 + 1*0.65 + 23*0.86) / (1.00 + 0.75 + 0.70 + 0.867 + 0.65 + 0.86) ≈ 15.31.
