Also displacement isn't measured in weight because a Freighter has the same displacement weather it is full of armour scrap or empty and the compensator field size is based on Displacement not Weight. Compensators make everything in the field weigh the same essentially, whether it is a full or empty freighter it accelerates at the same speed. If it worked on weight then one would have empty freighters moving faster than fully laden ships. But they do not.
Also it doesn't matter if the density of the shrike is 4.5 times that of the Highlander because density is not displacement. A Roland is not a ship that weighs 188,000 tons. It is a Ship that displaces 188,000 tons. But in a compensator field they both weigh the same, zero. Just as they do floating in Deep space. The Mass inertial is whatever it is but in a compensator field that is also essentially zero or a set single value. Being fully loaded with Mk16's doesn't make the Roland slower than when it is empty.
