Don't let the helicopter fool you. The motion of the rotor disc when the heli is on the ground, especially if it is restrained or if you hold it in your hand, is very different from the way it moves in the air. If you think about it, in the air the disk does not move very much at all _with respect to the helicopter_ because the heli's body moves with it. If you restrain the heli, the body can't move and the disc is like a gyroscope, it moves at different angles, and it strains against the dampers, etc.

So don't make any adjustments based on what you see the rotor disc do on the ground. To check control motion and travel, it is best to look at the swash motion _before_ you start turning the main rotor. The swash should move exactly as you move the cyclic stick, same directions exactly, and should be free to move to full travel of the stick.
Do not expect the spinning rotor to behave this way, though.
