I was not there in person, but I watched the replays on Youtube. I am relatively new to watching the sport so my judgement of height and distance is not great. So, for your comment about the 3-3s for SP i went back and watched everything again, multiple times, just to make sure I wasnt missing anything.
For Karen's 3-3, I agree with you that the 3Lz was prety much textbook in terms of height, distance.
For Wagner's 3F, this is the video I watched (other videos give a similar angle):

You will notice that the cameraman is right behind Wagner, so it's much harder to judge distance for her 3F. In terms of height, I did not feel that Karen was in the air for mcuh longer than Wagner, so no real difference there.
