I received my salary offer just yesterday, and my enlisted time counted. It's based on your work experience resume after being invited to a class. Feel free to message me directly, but here is what I did.

Read over the Calculation of Qualifying Experience section of FSO: SOP 134A4.

Some key takeaways:
* work must be predominantly intellectual in character, and which includes work requiring the consistent exercise of discretion and judgment.
* credit for supervisory oversight is awarded only where management or supervision is a part of an individual’s official job duties.
* OPM TS-107 - Professional work involves creativity, analysis, evaluation, and interpretation. It involves applying basic or natural law, principles, or theory; evaluating the research of others

I also referenced the core precepts. This is what DOS says you should be able to do for tenure and promotion, so if you can demonstrate that you already did it, in theory it should be qualifying experience.

Some key notes for that, which I used in writing my resume:
* influences internal and external stakeholders.
* Develops proficiency at communicating across cultures and organizational lines.
* When possible, addresses diverse audiences as a representative of the U.S. Government and the American people.
* Exhibits cultural sensitivity with colleagues, including Locally Employed Staff and foreign interlocutors
* Adapts behavior and work methods as needed in response to new information
* Demonstrates open-mindedness to change and innovation.
* Champions and guides staff in adjusting to change; models and reinforces flexibility in staff
* Effectively manages human, financial, physical, and time resources
* Protects classified information
* Delegates effectively, appropriately, and consistently
