How confidence is computedLower confidence
- Confidence
- Lower confidence, 62 of 100
- Evidence posture
- thin: No independent source documents this vendor's work; treat it as a candidate only.
- Capped by
- Rated from the evidence on file (sources, independence, confirmed quotes), not by an editor.
- Best position confidence
- Moderate confidence
It starts from the data completeness and source reliability of the profile, and is capped when independent proof of work is thin. The next level is Moderate confidence. One independent claim with a measured result for the best-ranked need is the fastest way up.
