I thought Harrington's discussion of M helped me a great deal. I understood the concept intuitively, but he helped me think through the details. His book is "chock full" of example hands and situations. While we each must find our own style, reading his discussions of how and why he would proceed should help any but the most experienced players.

I agree that the main point here is that once the blinds hit either 75/150 or 100/200, I must "pull the trigger" more easily. I do start pushing with any reasonable hand, understanding that either I will steal the blinds or be in a coin flip (or slightly worse) situation. When the blinds starting eating you, you have not choice. M just quantifies the damage!

So I do use M as a construct. More important than M is reading Harrington's thought process.
