For starters I can't see there being a great deal of turbulence there with the wind coming off the sea. Fixed wing A/C are inherently stable. He was in a high wing so lateral stability should be good. I say be lazy and let the a/c do the work. It will fly itself, as mentioned in previous posts.
From when he started doing the "Mayo" to when he touched down, the mayo would have been rock solid in that short time. He did appear to have nailed the centre line which was good.
If he was a pilot carrying out very low level ops performing like that, his left arm would probably have given up after the first sortie.
Maybe it's me being too old and out of touch. Please correct me should I be.
