@ Tim.

To correctly calculate the CG of the 757, go to the fuel and payload manager.  Next, count how many red lines it is to the center of dot (from top to bottom).  Then divide the number of lines you counted by 32 (total number of red lines).  Then multiply that by 100.  Round your answer to the nearest number.  That is the % that you enter in the FMC.

Hope this helps!
