I think that we can all agree that these charts indicate that the variation is due to temperature variations. Given that, they also indicate that NTP, as is, is too slow to react to temperature variations, taking something like 8 to 10h to compensate for them, even at 64s sampling period, it seems. The reference stratum 1 server, Feenix, seems to suffer from the same temperature-induced daily accuracy variations. Unfortunately, Mills will probably deny that this is an issue and will probably refuse revisions to his algorithm. If this is the case, perhaps it's time to add another algorithm alongside Mill's and let to the user whether he prefers Mill's algorithm or an alternative. Which alternative I have no idea, but I'd sure like to decide what's good for me, not Mills.
