Nope, not yet. I was trying to find out the exact same thing. At least to my knowledge. I did talk to the execs and they said they'd let me know when they want deliverables. I'm expecting sometime soon as the stuff for the application was due around June last year. I'm currently on a TDY so it's been hard to get face to face time with anyone at the squadron. From what I know, (last year) the execs wanted people to write their personal statements and have medical, PCSM, etc squared away so the CC could start working on their LOR and push that towards the group level for the Group CC LOR. From there I think your package goes to the wing and onward, but I'm not sure either!
