All the way 0_o
I don't see the difference. You try to survive and win all the way till you win. Haven you've been in the spot whrer you are the chip lead or 2-5th than 1 cooler from a whale and you are either out, or with 2bb? Unless the tournament has something like "50 places paid" structure, there i no place you can feel really comfortable
If you talking BB/(M) and the "plays" than the rough assasement is correct(but you should conccider M)
25BB+ - basicaly any hands to play, the reall poker if you will. you bully the table, if you can, steal, play gapers, and limp if you want
15-25BB+ - tigher ranger, no UTG raises with bad hands, any 3bet is somthing to conncider, small pairs are a question..
-15BB - Just wait hands/spots
but again you have to conccider who you play with, structure, how far is the bubble...
