So you do not need to be very exact about where you think the "allan-intercept" is for my method to work, within an order of magnitude is generally OK, and if you wanted to, you could add a third loop around the PI autotuning to try to optimize it over a couple of years. However, I am pretty certain that we can do better (and faster!) than that, by tuning until we get the right PDF shape for the zero-crossing intervals, if only we know what it should be. My math skills have not been sufficient to derive that. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
