I have a theory on the super quick approvals. They get there average time lower much quicker approving some new ones. Also, the forms I've seen come back in under ten days are stamped saying something approved by NFA something. They haven't been signed with the examiners signature. I had several under 10 day approvals before eforms shut down. Since it re-opened I haven't had any approvals.
They are all signed that way now.
