You don't understand man. If someone answered you and gave you a number, it would be pure baloney.
There are too many variables that can affect the yield.
It's like saying: "How far will a car go on one tank of gas?"
Which car? What type of gas? How big of tank? What altitude? What driving conditions? What kind of tires? How big of engine? And on, and on, and on.
Read up on LST some more, and on vegging and flowering weed.
If you tell me most of the variables that fit your exact grow, then I can tell you the difference in yield between using LST and not using it.
Here's the list of variables that could affect the yield:
