An estimate is a starting assumption, not a capacity promise. Add replication, metadata, indexes, protocol overhead, and growth margin for a production plan.

USE THE NUMBER, NOT THE VIBE

Back of the envelope estimates narrow the design space. They do not replace a load test or a measured workload.
