As above - where/what looking.
The earlier you can see a tiny pitch/roll change, the smaller the control input required, to stop/correct that pitch/roll change and prevent it becoming aircraft movement.
So you have to be looking at something that equates to cabin attitude and horizon. Eg the compass and the tree tops.
Once the AC is moving, it requires a bigger control/attitude input to stop, then a second input to re-select the hovering attitude.
