Based on our experimental measurements, our servo is capable of generating 34oz*in of torque.  The servo is able to rotate over a total angular displacement of 110 degrees.
With the addition of our counterweight, our lift arm is capable of applying a maximum torque of 59.2oz*in, since the counterweight weighs 2.4 oz and is approximately 10.5 inches away from the point of rotation of the arm.  The weight, at 16oz, is 3 inches away from the rotation point, opposing the lift arm with a torque of 48oz*in.  Thus, 48oz*in of the maximum torque are used in lifting the weight.  The percentage of the max torque used to lift the weight is 81%.
On the basis of conservation of energy in an ideal, frictionless environment with no deflection of truss, the servo is capable of lifting the weight 4 inches.  Including the potential energy gain from the counterweight, this ideal maximum lift distance is 5.4 inches. 

Our final design consistently lifted the weight over 2.5 inches, and, on several occasions, the lift height exceeded 3 inches.  Thus, our design achieved approximately 56% of its theoretical maximum.
