Control Surface Loads

In designing modifications to planes, I have found that the servos specified have significantly higher torque capacity than that needed for my flying. My Goldberg EX-TREME 330 3D recommended standard servos or about 40 oz.in. torque. My calculation using a servo calculator program indicates I need only 3 oz.in. torque for the elevator and my flying conditions. I am very comfortable flying with the 17 oz.in. torque servo currently installed. This way I save weight which is important in my Epowered models. I welcome any experience that would confirm or correct my findings.
