I recieved a 40% rating back in May 2020, for Vietnam service/Diabetes/peripheral neurapathy. I did the intent-to-file in August 2019, didn't get my C&P until nearly Dec 2019, and then finally in May 2020, recieved the 40% rating.
That whole claim cycle took nearly 9 months..
Fast forward to now: I put in a Tinitus claim in early July of this year, within a couple of weeks, I was notified for the C&P, and within days after the C&P, I got the decision letter for 10% Tinitus. Though due to the wacky VA "math" I got zero $$ increase there.
Since my hearing is shot besides the tinitus, I decided to put in a hearing claim around the middle of September. Again, I was notified of the C&P exam within less than two weeks after filing, and yesterday, I got the decision letter... 20%, putting me now at 60%.. Impressed..
