How does "Burn Accuracy" work?

@LeMagicBaguette That's one way to force people to use the Oberth Effect.

Burn accuracy seems to be a function of the burn time against orbital period. The higher the ratio, the lower the accuracy, for a burn only works if you're moving in one direction, and the longer you burn, the more your velocity deviates, throwing off the intended direction of your final velocity.

As for gravity turns, it really depends on how high off of the ground you want to orbit. I haven't really tried it, so I go off of vibes.
