30% To 70% Question

[mojo13]

I files claim back on 8/30/10 effective date for PSTD and was granted 30% on 3/7/2011. On 3/23/2011 I sent a NOD to RO indicating my support of a higher rating witch was received by RO on 3/24/2011. On 12/14/2013 was granted an increase of 40% too 70% up from 30% and now rated at 70%..My question is this they are only giving me my reto from my last C&P which was 9/9/2013 4 months. My effective date was 8/30/10 and NOD dated 3/23/11. I have been fighting this increase for close too two years, showed them by med evidence that my PSTD has gone hay wire why did they only grant me 4 months retro instead of reto from 8/30/2010 from which I first claimed

If you send in one shred of new evidence with your appeal the VA will use the date they got the new evidence as your new effective date for the increase. I don't know how this is proper but that is what they do.
