Nose wandering on fine sighting adjustments

[engarde]

I'm finding that when I adjust sightings on aircraft right before shooting, the sight waves suddenly through the target along the line of adjustment, causing me to zig zag around behind the target like a kid waving a sparkler in front of his face until i end up with some kind of aim, and commence firing.

I am utterly aware its most likely my joystick.

Occasionally i can get fine progressive aiming where i put a stream of shots into the target instead of stitching a line across it, although I think thats just me not actually registering a control input to my ultra feather weight just breathe on it attempts to move aim.

Yes i have adjusted sensitivities up the wazoo. No joy.

Anyone else find this? As i said, i believe it is my not expensive but not that cheap joystick, unless someone can explain a possible reason.
