the port stabiliser makes a different line with the TE of the wing than does the Stbd.
Lyman, in which of the 4 pictures posted do you see this?
Take powerpoint and mark up the picture you think this is most obvious.
Be sure you are not looking along the trailing edge line of the elevators. You have to look at the leading edge of the stabilizer to show actual tail twist relative to the wing, probably by lining up the corners of the stabilizer LE tips.
If the port elevator deflected as much as I suspect it did, it may account for the left roll at the beginning.
