That guarantees for you never become a really successful player in any level. It is not even tight, it is total insane. Most of the times the blinds are going to eat you, as most of the tourneys built up in that structure, that in the bubble you must steal by using your hole stack.
Against most of the cards in hand, you still will have 30-40% chance to win with mid range cards...
It is okay online in satellites, if you have enough chips to sit out the prize, I do not see it worthy in any other case.
In my opinion, you must have less tight range in bubble, than at the beginning or any other phase of the tourney. Of course, if you want to win it or at least reach top 3.
