"Acceleration increased during S-IC flight for two reasons: decreasing propellant mass; and increasing thrust as F-1 engine efficiency improved in the thinner air at altitude."
This is from Wikipedia, so who knows. Why would a thiner atmosphere increase the thrust efficency of the engine? Something to do with the ullage space in the tanks not needing to be filled with atmosphere?
