As it should - the reading is the voltage applied to the trailer brakes, which should be in proportion to how hard you are decelerating. Unless you are very steady on your brake pedal force, your braking effort will change and so the trailer braking will change.

The trailer shouldn't drag on the tow vehicle at all. The idea of the trailer brakes is just to have the trailer do most of its own braking, so braking with the trailer shouldn't be different from braking without the trailer, but with a significant cargo load.
Another way to put this: without trailer brakes, you would feel the trailer trying to push you down the hill; with trailer brakes, you shouldn't feel pushed. Applying the tow vehicle's brakes should
not feel like you are throwing an anchor or parachute out the back, although if you manually applied
just the trailer brakes (something you do only for testing as mentioned in an earlier post) it does feel like the trailer is acting as an anchor or 'chute.
If find with my 3000 lb trailer, my Sienna van, and a Prodigy controller, that the first level of boost works well on the highway, but is "grabby" in low-speed urban conditions. I have turned it on and off to suit the situation.
