You are NOT basing your training off of your max so why would you add to your max? You ARE basing your training off of your training max so you would add to your training max. Don't mix them up.
I would go read more about the TM from either Jim's book, website, forum, or any article he has written or podcast/interview. Your max and TM are two different things. One for training, one for competing. Don't mix them up.
