I did not do and complex math equation, I just used a 1/72 scale resin kit for reference. This is one link I used, (https://www.hobbyworld.at/homepage/modellbau/science-fiction/star-wars/xs-stock-light-freighter). The ingame model for this ship is way oversized in many peoples opinions. So I scaled it to be roughly double the size of the Falcon, and not 4x the size. Built the model is 11 inches long. Those ingame pictures show how oversized the ship is. Just look how tiny that person is lol.
