For servos, can it be implied that Holding Torque = Operating Torque * 2 like with steppers?

I am following a guide that recommends using stepper motors and it has an approximate holding and operating torque. It says that if you don't know the operating torque, it is often half of the holding torque. I am adapting this to use with a servo and I was wondering can this same formula be used with a servo. My servo has approximately 1.98 kg/cm of torque so does that mean that I can estimate the operating torque would be ~1 kg/cm?

A couple of things:

• I know operating torque and holding torque are different. This is just a estimate-it isn't an exact science.
• I know servos are harder to find their location (75 degrees, etc.) than to use a stepper and assume that it worked. I have external means of finding the location.
