You’re actually wrong about this. Here is the way it works…
If they can take away whatever your referred conditions are, and your total percentage remains the same, they will not recoup. (Unless your ratings change in the future, then check again)
For instance, I was 10% DoD and 100% VA. Taking away the 10% I still remain at 100%, so they aren’t recouping.
Let’s say taking away the 10% caused me to actually go to 90% though, then I would actually receive 90% VA disability and the difference between 90% and 100% goes towards recoupment until it is fully recovered, then I would get my 100%.
