In multitable tournaments its not really important, what your position in the entire tournament. Its much more important, what your stack is compared to the other players at the table. For the moment you are really only competing against them, so understand when you can apply pressure, and when you might need to back off a bit.
Lets say you are the table chipleader. Early in the tournament that hardly even matter, since everyone are just focused on increasing their stack, and nobody are afraid to bust just yet. Often people can even just reenter, if that happen. Fire another bullet. When late registration has closed, and the bubble is approaching, people tend to get more focused on surviving. And this is where, you can sometimes be the "chip bully", which everyone loves to hate.
But even then there is a huge difference between having 12.000 chips, when the next on the table have 11.000, 10.000 and 9.000 respectively, and having twice as many chips as everyone else. In the first situation you cant really go to crazy against the guys with 9-11.000 chips, because if you do and lose, then suddenly you are the one, who is at risk of bubbling the tournament. The same principles apply on the final table.
