You have to count on a huge amount of folding equity or a lot of dead money in order for shoving with any 2 in the CO to be correct. When there is so little difference between 9th place and 6th place, and many of the players have even shorter stacks, you will often not have that folding equity, and shoving with any 2 will often drop your M further. Indeed, one of the ways you could end up with an M of 5 is if you started with a larger stack, and kept pushing into short stacks.

Over and over, people try to ignore that playing with a short stack (here, one that is greater than the table average) is a normal part of tournament poker, not a sign of shamefully bad play. Good players should often end up with short stacks at some point, and if your goal is to win money, you should know how to play a short stack well.
