The only thing I could offer other than what DAA has said is stuff from my COTP process which was a decade ago.
However, I know that, for several years now, there has been aspects of the draft 5002 DAOD that have made their way into the VOT processes. The DAOD is still, AFAIK, a draft, hence the use of CFAO 11-12 as the reference. If the current AVOTP message states CFAO 11-12 as the main reference, then common sense would tell me that any PSO with a shred of ethics would go by the CFAO (this is what happened in my case; some superiors in my CofC tried to stonewall my OT application when it was determined that my old trades' Career Mgr informed them that, as a Pri 4 unit, he could not post anyone in to replace me). However, either via PM or on this thread, I think one person who is (I believe) a PSO stated that interim policy was signed off by the CMP and that policy is being used over what the CFAO states. My experience with these issues tells me it wouldn't stand up to a formal challenge or review, such as a grievance.
I haven't looked at this years AVOTP CANFORGEN, but do your homework, remember to be polite and proper military bearing, etc when dealing with the PSO office. Ask questions. "The CANFORGEN says that CFAO 11-12 is the reference for Reg force NCM remusters, but the term OFP isn't found in the CFAO. Where is the policy that states OFP shall be used, and can I have a copy of it please".
It is also helpful if someone in your CofC is supportive of your position. Cross your Ts and dot your Is, and ask for assistance from your CofC if you can if/when you hit walls.
