Oh please. That is just a terrible, terrible thing to nitpick. The text as written is just an imprecise measure. Unless RFC gave an exact percentile difference between the tonnages of the two ships, it should have been blindingly obvious that the number is rounded to an appropriate, text friendly fraction.
EDIT: I also cannot find any reference to the tonnage ratio in the text of SoS or SftS. As far as I have been able to determine, Aegis was only identified as an Avalon class and that it was "almost as modern as Hexapuma", and the only time her tonnage is ever laid out is in the Companion.
