| Scope | Meta's February 2024 SPTP report gives fleet offset-from-master distributions for more than 100,000 clients, with the sub-microsecond values presented graphically. Treat it as the target the acceptance sweep must demonstrate on your own fleet, under load and across every node, not as a standards threshold. |
