"I believe I am right in saying that you have agreed that the lady is more to her left than a few years ago.. Didn't you use the word offset. Doesn't it stand to reason that in that case there has to be a change of position, for the ladies left hand. Where else can it go."
More in front of her own body. In effect, if she offsets her body more, she will feel more like she is dancing in the crook of her left elbow. This is quite the parallel of what the man needs to do for a big look - not stick his left hand way out to the side, but rather dance his body closer to his left hand. As they sometimes say, feel like you are trying to put your left thumb in your ear. Or may I should say, your ear on your left thumb. Space between the heads makes you look big... but arms way outside your bodies just makes you look dangerous.
"Anybody who has seen the pictures from the International will also see the change in shape of the ladies right arm. Its pretty straight."
If you watch Mirko & Alessia, her right arm is NOT straight - it is quite nicely bent, because his left hand is close to his head and not way out on its own. However, there's a video out where they do a series of pivots, and during that you can see that their elbows straighten a bit, and only recover position as they return to more linear figures. Nobody's perfect.
