It sounds to me that you are looking for an excused to not to succeed. If you truly want to save you M then stop looking at numbers and start working on the techniques in the DBG/DR. You must redirect you negative mindset to a positive one. I am not saying you will achieve your goal of saving your M, but you can truthfully say that you gave it your best shot. You don't want to wake-up one morning, saying to yourself, I wish I had done more.
I have had the same feelings that all of this hard work that I am doing on myself and my W will not work. That I will end up alone and having to start all over again. I am scared of that, so I can't give-up until I have done everything I could too save my M. I have had some success and I have had some setbacks, but I keep going.
Don't worry about how many Hs come back versus how many W. That will not help you save your M. Only working hard to save it will get you where you want to be.
If you don't like the odds then CHANGE THEM by saving your M
