I agree with Juhana; the interesting figure is 7 ms. The reason for this is that if 7 ms happens often enough to be registered within the period of a normal benchmark/test, then it's happening way too often! 7 ms has to be regarded as the practical worst case latency, and it's too much even if it was guaranteed never to occur twice within say, 5 seconds. (Allowing RT thread to catch up so that another 7 ms peak doesn't generate a drop-out.) Once in a few weeks may be acceptable. Once in 10 hrs, and we don't have a seriously usable solution.
