The assertion of a +/- 7.4 ns systematic error is itself rather interesting. In this case, how does one estimate a systematic effect as a deviation, standard or otherwise, and wouldn't it generally be the case that such errors would be biased one way or the other as with the three effects (dilation, Doppler, Sagnac) discussed in the preprint?

Whatever error(s) they have committed it is likely to be rather "unsystematic", whether or not it is trivial :-)
