Live small MTT rebuy strategy

[RacersEdge]

I had a similar question myself on Friday in another thread since I never played in a re-buy. (The FAQ was very general.) Makes sense to re-buy becasue it sounds like it's almost just part of the original buy-in - i.e. in this case, you are basically buying 3000 chips for $75. Seems like a disadvantage to hover around say 1050 chips and never go below 1000 during the re-buy period. Is that the case?
