Some thoughts I've had:
1. Weathercocking - I thought that was unlikely, since an larger gust would have put the nose more to the right but see below.
2. LTE - no, because the nose would have gone right again, and the Nr was up at the top of the green.
3. Collective pitch reduction - not that I recall, I was just coming to the hover and the lever was coming up to a "normal" position for the power required.
Only thing I can think of is that with the wind from the right, and a relatively heavy a/c I had a LOT of left pedal in. If the gust was just BEFORE I arrived and dissipated as I came to the hover, then I would instantaneously have had far too much pedal.
Droopystop - what more info is needed, I'm quite happy to provide it.
