Relationship coverage
Burgess’s master question at named-account scale: of the accounts that matter, how many do we have live relationships inside, how deep, and how warm? It replaces response rate entirely. Measured on two axes: the scoreboard stage each account has earned (breadth across the list) and account depth (strength of the warmest relationship inside each account). Stages are earned by the buyer’s action, never by your send.
