Thanks, y'all, for the replies.
I think I understand the combined rating based on symptoms. The only reason I filed for PTSD is that I could not get a definitive diagnosis. Someone said, when I was in the domiciliary, that I could only get a diagnosis if I filed a claim. It seemed like the VA was beating around the bush by repeatedly screening me for it with a few questions but never giving me a true diagnosis. I got the feeling the VA and DOD were trying to downplay the numbers on veterans and service members from current deployments with PTSD. I guess I also filed because I lost my TS/SCI clearance just for going to mental health while I was deployed. That eventually cost me my civilian job I had after I de-enlisted; twist that knife Army! It burns me up to think of how many people were done this way and the Army got away with it. (end of rant)
Right now I'm rated at 50% for major depression. Looking at the report on my PTSD C&P and the rating schedule, I don't see how they could possibly go lower than 70% for it. What I was attempting is to get that 70% to go back to my last rating for depression. This was actually the case when I originally filed for PTSD. They denied that claim because I didn't have proof of a stressor. However, they still gave me a C&P and higher rating for depression based on the PTSD claim.
As far as the deadline, that was the 10th of this month. Yes, it's a risk, but I'm pretty sure that the PTSD C&P report will get me up to 70% as new and material evidence.
Wait. I'm really confusing myself. The 50% rating for depression resulted from my original claim for PTSD. I got the PTSD C&P because I asked for reconsideration after the VA decided to concede the stressor withing a year of me filing for PTSD. That means, if I get rated higher than 50% for PTSD then it WOULD go back to the original claim date. If that's the case, wouldn't the I/U go back to that time also? Even if I had not implicitly asked for it?
Okay. Sorry for getting so far away from my original question which was if I was slowing the process down by filing all this in rapid succession.
