Even substantially derated, I wouldn't expect a problem in the short term as the flattened area of the adjustable loop is only subjected to 1/2 the weight.
Once the SRS has been used many times is when I would feel concerned. At that time, a given area of the rope may have been flattened several times and due to varying hang distances could end up between the hammock and ring where it would be subjected to the full force being applied.
