I have run into a problem a few times with TWR calculations and the rocket not preforming to spec. For instance, I use data and numbers provided on the ksp wiki and the in game thrust and weight figures. My latest instance of this problem was when I had a rocket with a supposed TWR of 1.43. Which means that the rocket should have seen, at full loading and 100% throttle, an acceleration force equal to 1.43 gees. The rocket, however, felt like taking a day off and not launching until it burned through a tank of fuel on each of 5 engines... I then went and checked my math with a know working real world rocket and I was not incorrect... so my question is... What gives?
