G'day Markc80,
I agree with all the previous posters and add that it looks they are flying in fairly choppy conditions which can lead to quicker control inputs, also it could have a little to do with personal technique.
Some pilots have a more relaxed style and operate the controls really smoothly while others are a little more urgent which tends to result in more rapid control inputs.
Regards and good luck with your training, it's a long arduous road but we've all done it and it's well worth the effort,
BH.
