Methodology and sources
Method note and sources
This score uses the boutique public-evidence rubric: state license (25), professional directory (20), verifiable transactions (20), years in business (20) and public reviews (15). A number is published only when at least two criteria have a source and at least one of those sources is independent of the firm. With exactly two sourced criteria the score is capped at 9.0; a 10.0 needs at least three. Self-reported career totals and review claims we have not read are not inputs.
