It does appear to be drifting more than acceptable, but keep in mind wind really messes with the quad. Plus factor in weird turbulence caused by trees and other object in the path of wind.
Wind can easily move it 2 to 3 meters before adjustment is seen, especially if gains in assistant are lower (spongier response)
I took mine out tonight and initially it was worse than yours. It was making rapid adjustments as the wind was rolling over the orchard trees next to me.
Took it up a little higher, it was still twitching around but nothing like the initial hover by trees.
To give a fair test wait till calm and get it into a clear open space. Plus with all those taller trees around I'm curious of your satellite count.
