Yeah i see what you are saying stormswa, but i think it can also be answered as a generalisation, which i did try to do, yes it does depend on a lot of factors, but i think staying above the average stack, does set a good benchmark for which you can base your hand selection on.
Also you disagree with me changing my play to reach the next pay level, and yes i partly agree that we don't want to get blinded away just to get to the next level (please note that i would not take this to extremes, and would play any decent hand if i thought i had a good chance of winning the pot), but in a tournament where 27 are paid,the pay level between 27th to 19th can be a 1/4 of what it is for 18th to 10th, so in this situation it can be the difference between 2 times the buyin and 8 times the buyin. Also i use this strategy as part of final table play, where the pay difference can be quite significant, (although i realise this wasn't what i was talking about in my original reply, so not a valid point in this discussion).
