Well your best bet is going to be recording your fat content for use in your formulations. Along with the variables you mentioned above there is also how much trimming is done by you or your supplier. Then there is a marble rating, that will effect the fat content.
So I have a variable called fat content in our database that allows us to enter an average fat content based on the way we use, trim and select our cuts. So each cut has a fat percentage that is calculated in the formulation, along with the added pure fat to give us a final percentage.
The only way to get an accurate measurement is if you use something like a computer vision system that analyzes the marbling of each cut as it passed under a vision system. This is how a more exact calculation can be made in commercial operations where the fat content must be controlled fairly accurately.
Your experience and consistency in how you select and use your cuts is going to be your best bet, IMHO.
I am the master of my fate:
I am the captain of my soul.
