is your "M" really important?

[jaydoggie]

i know since HOH people have been using this term alot. first of all i find calling this calculation "M" is annoying. i hate hearing My "m" is..

secondly doesnt this significantly different than just saying..20BB. i almost never when playing in a tournament worry about how long its going to take me to blind out.

i do understand the importance of stack size, just the stupid term "M" that makes me stop reading posts.

this isnt intended to be a flame or rant i just want to know actually if it is that importnat. if youre "M" is 5 or lower consider yourself short stacked why does this have to have a new term?
