BUZZBERG Alpha Score combines three things: realized average return, confidence in the sample size, idea volume, and speaker reputation. Speakers with only a few calls are pulled closer to the platform average; speakers with many evaluated ideas keep more of their own return. Reputation only boosts: 5.0 or lower is neutral, while scores above 5 add weight. Scores are normalized to 0-100; 100 is best. Read the FAQ
