Maybe to account for the fact that a rolling game piece is moving half as fast as the conveyor? Maybe for safety factor? I'm not exactly sure.

OK I get what you are saying but it DOUBLES the current draw and I would think a rolling game piece would reduce the current draw.

It could be assuming you're attempting to lift the object rather than just draw it in (IE, an intake that feeds up into a hopper or something). Perhaps in addition to loosing 50% of the speed of the roller, you also loose 50% of the torque?
I suspect sticking a 150lb ball into an intake roller is going to present some different results than using that same roller to winch up a 150lb robot, whatever the case may be.

If you want the correct answer to the question of what that tab assumes, I suspect you might have better luck PMing JVN.
