Thrust per ton?

Well, sounds like alot of work for tomorrow. I'll try to give as much info as possible.

Maybe he is accelerating too much ?

I'm used to keep a reasonable TWR ratio (Thrust to Weight), but how much fuel could one be loosing if that person was burning red from 15 to 30 km ?

This is the only reason I see for loosing more fuel during a gravity turn than with a straight-up launch.

Beerkeg, don't forget that even if you don't reach the Apoapsis as fast as before doing a gravity turn, you'll still use less fuel to circularize your orbit.

Typically you need around 4600m/s of Dv minimum to reach orbit. Meaning that in Mechjeb every stages used to put the ship into orbit, need a summed-up Dv above 4400m/s. After that you need 900 to reach the Mun, 200 to circularize, 8-600 to land.

I suspect either thrust to weight is too low for one or more early/mid ascent stage (which I've done to myself; feels like you just can't get enough fuel no matter what you pile on), failing to stage off empty portions of the ship quickly enough (again, eats up fuel you need for the rest of the ascent), or has a thrust to weight ratio that is way too high (air drag causing the engines to eat fuel like candy due to how the game handles thrust vs drag). It could be more than one of these things working together considering what he describes.
