say that JR rates a servo at 100 ounce inches of torque measured at 1" away from the center of the arm. Let's say that servo made by XYZ company also lists their servo at 100 ounce inches of torque but the measurement was taken at .5" away from the center of the arm.
It does not matter what the servo arm distance was when measured.
If one company measures 100 ounces at 1 inch, that is the same as measuring 50 ounces at 2 inches or 200 ounces at .5 inches.
If a servo made by XYZ lists there servo at 100 ounce-inches, but made the measurement with a .5 inches lever arm, then they measured 200 ounces FORCE at the .5 inch lever arm, which is still 100 ounce inches of TORQUE.
