Okay. I would like to thank everyone for your answers. But to clear up confusion, I have to ask. Since dV is a function of thrust over time, do you not think that what MJ shows is the time it takes to achieve the delta shown? It would make sense to me. It would also explain why the time decreases with better thrust to weight ratio. @Kelderek Thank you for mentioning the TWR. It was 0.35 which is a complete joke.

Hello. I am trying to build a fuel efficient craft. But my understanding of delta-v and how it works is flawed. I am using mechjeb.2.0 So here are my questions: 1. Does anyone know what does the time represent? Is it the total burn time? How is it related to Delta-V 2. Does Delta-V calculation account for weight? Do the delta-v requirements for maneuvers increase as the weight goes up? The issue is that I managed to get high delta-V which was around 6K on my previous rocket, but once leaving the atmosphere I had issues hitting stable orbit, because the engine was simply not strong enough to do it in a reasonable amount of time, so I got trashed by gravity. I would appreciate if someone explained all this in detail. Thanks.
