Ok if your ratings were finished on the 2nd, they went to the PEB on the 3rd. It takes the PEB 2-4 weeks to put everything together and issue a 199.
When you packet goes from VA to PEB it goes in a digital stack of other SMs in the process. Once your file is at the top, the board reviews your case and the VA ratings. They can agree or disagree. 99% of the time, they agree. Now they go to work dictating your 199. After it's all on paper, they review it and sign it. The next day it goes out to your PEBLO.
The thing you have to remember is you are not the only one. There are many others and if they are backed up, it takes time. I received my 199 25 days after the VA finished my ratings. You are at 21 days. It will come this week or next week. If you haven't seen it by Thursday of next week, ask your PEBLO one more time. If she gives you no information, I will give you the number for a PEB analyst at the PEB and they will tell you when to expect to see it. If you don't want to wait, search the forums for my posts and you will find a couple of posts I already provided the number in.
