What are the internal integration settings for the built-in force calculation feature in the MF interface?

I am trying to use the built-in force calculation feature for a magnetic fields problem (mf interface) in version 4.0a. The documentation states that COMSOL integrates the Maxwell Stress Tensor around the boundary of the object on which you want the force to be calculated. I have successfully confirmed that the calculation matches my own calculations (using the Line Integration feature in the Results node, and defining appropriate stress tensor components int the Global Definitions node). When I use the Line Integration feature, I am able to choose the integration method (integration or summation) as well as the integration order. However, I can't seem to find any documentation anywhere that states what the settings are that COMSOL is using internally. I would like this information so that I can quantify the expected error in my computed results. This should be a quick answer for someone who either works for COMSOL or who has worked with the Maxwell Stress Tensor Force Calculation feature a lot.

Thanks.
