Regarding the Armed Forces Reserve Medal, how many years of my service would apply to it?

You'd think it would be pretty straight forward but perhaps not so much. See, when I was commissioned in 2000, I was commissioned into the reserve component (for those that understand Navy Officer designators, the last number of my designator was a 5 (1105, 1175, 1125). At the time, they were commissioning all new officers, even those going on Active Duty, into the Reserves and then after a certain period of time (5-6 years) "augmenting" them into the Active Component. Well, it was around the time I would have augmented that I left active duty and became a drilling reservist. My designator stayed the same (1125) and I have drilled continuously ever since. So, right now I'm either at 18 years of reserve service or 12 years of reserve service depending on when you start counting. Does that first 6 years of being on active duty but in the Reserve component count or not count. Either way, I'm wearing a bronze hourglass right now. But do I go up to silver in 2 years or 8 years?

Here is what Executive Order 10163 says about the matter...

"3. The Armed Forces Reserve Medal may be awarded to members or former members of the reserve components of the armed forces of the United States, including the Coast Guard Reserve and the Marine Corps Reserve, who complete or have completed a total of ten years of honorable service in one or more of such reserve components, including annual active-duty and inactive-duty training as required by appropriate regulations: Provided (1) that such ten years of service is, or has been, performed within a period of twelve consecutive years, (2) that such service shall not include service in a regular component of the armed forces, including the Coast Guard, but (a) service in a reserve component which is concurrent, in whole or in part, with service in a regular component of the armed forces shall be included in computing the required ten years of reserve service, and (b) any period of time during which reserve service is interrupted by service in a regular component of the armed forces shall be excluded in computing, and shall not be considered a break in, the said period of twelve consecutive years, and (3) that such service shall not include service for which the Naval Reserve Medal or the Marine Corps Reserve Medal has been, or may be, awarded: And provided further, that any medal awarded hereunder shall be of the design distinctive of the reserve component in which the person to whom it is awarded is serving at the time of the award or in which such person last served."

It says that service in an active component is excluded however it also says. "but (a) service in a reserve component which is concurrent, in whole or in part, with service in a regular component of the armed forces shall be included in computing the required ten years of reserve service"

So, was I in an active component? Was I in a reserve component? Was it concurrent? Seems to me it is but I'm unclear on the interpretation here.
