Got knocked out following HOH advice

[el_grande]

..or did I? Was this a poor interpretation of inflection points?

I was playing in a $5 party tourney with 250 to start. There are about 45 left with 30th place being in the money.

Stack is about 8,200 which is just below average.

Blinds are 400/800, so my M is under 7 meaning I am well into the orange zone, borderline red.

I'm in MP with KQs at a fairly typical (somewhat tight) table. Folded to me, I go all in.

Should I have just called?
