Actually, I've noticed that this simple "chart" is nonindicative. Zy and Fura'ngle are similar in technological advancement, but Zy ships were designed purely for war, while Fura'ngle were not. Fura'ngle (I assume) jump technology outclasses that of CSA (as mentioned in M04), Nordera can take a lot of hits, way more than Cordi. In fact, "technology level" concept known from RTSes doesn't really seem to apply here, each race has it's strenghts and weaknesses. Not to mention Fura'ngle are alien enough to have nothing in common with how other races developed and there was plenty of technology sharing.
