Pretty much never. I've gone from chip leader to out near the bubble a couple times in satellites. Near the end people all stall hoping someone else goes out first. The side effect is that the blinds escalate INCREDIBLY fast relative to hands played. Within a couple orbits you can find you're in danger again...then one bad hand and it's all over.

You've got to keep being aggressive and pick on people trying to coast in. Pick on those mid-level stacks who are afraid to bubble out. Don't pick on the small stacks, they want to double up. And obviously, don't pick on the monster stacks that can swat you like a fly.
