Anytime throttles are actuated with a arm there will be a change of rotational velocity relitive to the angle of the arm...
running some numbers in excel, comparing a throttle arm set for +/- 45 degrees with a wheel shows at the begining you get more butterfly opening for less pedal. while the wheel looks like a small advantage in linearity, the great advantage is the reduction of the force resulting in loading on the butterfly bushings. at 45 degrees, the force that results in forcing into the bushings is equal to force being used to rotate.
when I get some more time I hope to add a 2 arm arrangment into excel
