There is no way to confirm/verify, "over-working when above and under-working when below the peg". And proposals are made with consideration that hbd will be $1 and costs were estimated accordingly. So anything DHF over paying could be returned to stabilizer, that’s basically what we started to do. So you are still covered for development and also helping to decrease supply/increase future funding by sending back to stabilizer. Beside in script we can add threshold parameter for downside risk and stop returning HBD when it is 20% or 10% close to peg.
