Under My Accounts & Prospects, the Buying center coverage section shows how well-covered each account is by contact count: Single-threaded (one contact known), Low-coverage (a couple of contacts), and Full buying center (several contacts across roles) accounts, each shown as a total count. This is a fast way to spot accounts where you're relying on a single relationship and should be prospecting for more contacts before a deal stalls on a single-threaded champion.
