OK - this matches both my observations and my intuition. But, I don't
see why this is so. Mathematically, it seems to me that a gravity
turn is independent of whether the vehicle is under power; and that ,
second for second, the trajectory will look the same, powered or not.
What is different is the proportion of the flight that is powered.
Can someone resolve this paradox?
