Smartsheet: User Rating (average)

Each source is treated as one opinion; for sources with multiple ratings, I computed a confidence-weighted average to produce a single per-source value (Source1 ≈ 4.45, Source2 ≈ 4.17, Source3 = 1.40). I then combined these using the sources' average confidences as weights (Source1 0.85, Source2 ≈ 0.917, Source3 0.90). The resulting weighted average is about 3.324, rounded to 3.32.
