I wouldn't bother if you don't want to rebuy or add on at all. The average player is going to have ~4x the initial chip count by after the first break and the chip leader will have at least 8x. Even if you play well it's going to be hard to get that many chips without rebuying or adding on. After that point, even if you double up you are barely even going to be average let alone in good position if you start with so little chips.
