Appeals Granted and Effective Dates!

Hi All! So this just happened yesterday when I was checking Ebennies. Granted appeals from 2014/2015 and a change in effective date for my PTSD! Waiting for it to settle and will probably appeal my most recent migraine claim (still waiting on letter of denial).
90% (91%) overall still but one step closer to 100%
It’s been a long time coming, but thank you to everyone on this forum!
If my horrible math serves me right, back in 2011-2014 I was at 40%, having PTSD rated at 70% and the other approved appeals would bump me up to 90% since 2014-2015. So backpay would be from 2014-2015 to 2019 for the difference correct?
