itself during descent, even when the Super Dracos aren't firing. This

And how many stage 1s were lost before SpaceX got it right?


Irrelevant. The problem with Falcon core is the engines aren't deeply
throttleable. Dragon V2 with Super Draco doesn't have that problem.


In terms of landing accuracy, can landing from a full orbit altitude be
as accurate as landing after a 3 minute flight where speed during
re-entry is much lower so minute deviations in angles etc have far
lesser impact?


Of course it can. Dragon isn't just a rock coming back.
