This method is not absolute truth, but it will take you in the ballpark. The most difficult thing to find in launch setting is correct combination of tow hook and elevator positions.
Beware, this is only true if the CG and the towhook positions are actually quite close to each other. Can lead to disaster if towhook is well aft of the CG.
