Mass
I compared some in-game sampled ∆Vs with calculated ∆Vs (using the rocket equation) on a low mass orbiter (w/3 thruster blocks) and found that my sampled values were on average 4.3% higher than the calculated values. If I used a mass of 0.005t (for example, instead of the stated mass of 0.05t), the values only differed by 0.06%.
