What is the method of calculating the efficiency of double deck screen?

Basically the same as a single deck, except the feed to the second deck is the under-size from the top deck. You would normally look at the efficiency of each deck separately, unless you are using the top deck to take a load off the bottom deck, then you would consider the bottom deck under-size as compared to the total feed. (or combined top and lower deck overs-size if using the screen to get rid of fines).
