The error statistic currently uses smoothing factor of 0.02, so it should adapt to the new jitter at most in few hundred updates. In a simulated test with ptp4l where jitter is switching between 10 ns and 1 us in 1000 update interval it seems to reach the maximum number of points in about 20 updates and it goes back in about 200 updates. http://mlichvar.fedorapeople.org/tmp/ptp/linreg_adapt.png > Also, any reason not to merge this right away, to let people try it? If you don't mind including an experimental code, I'll be glad if more people test it. -- Miroslav Lichvar ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
