This still seems pretty misleading, as for example

sounds like it might mean bytes per *active* connection, when of course
the correct way to figure it is by multiplying by max_connections.
If you're going to give a formula, why not just give a formula, eg

    (1800 + 270 * max_locks_per_transaction) * (max_connections + autovacuum_max_workers)
