would say
in tournament it is really not important how many big blinds you have.
the most important thing is , other player knocked out earlier than you.
with 1 chips you can still win 2nd or 1st.
so my answer try your best to survive in a tournament.and try your best to make others potentially being knocked out earlier than you on purpose.
so any legal methods are allowed, including, slow roll, clocking, shut down router on purpose to manually delay, and steal blinds, etc etc.
try to think this, at 10BB blinds 100/200, average stack 2000, you have 1000, you are in bad situation, but if you clocking purposely to blinds 250/500, average stack is 2000, humm would say you are not in bad shape, some 1500, 2000 even 5000 chips player would be a little worry.
