Score: the overall ranking. It combines popularity in your peers, specialist fit, stay rate, switching momentum, and peer closeness. Higher is better (use it mainly for rank).
Peer fit: among the results shown, this tells you whether the firms choosing this accountant are the closest match to your company (higher = closer peers).
Stay rate: when peers had this accountant last filing, how often they kept them next filing.
Specialist fit: how over-represented this accountant is in your peer group vs the overall market (e.g. 1.42× ≈ 42% more common).
