Indeed, as you want to free roll the slippery areas and not have brake applying when you dont want it. Unless you want to ride the throttle (not enter dead band) which is hard to do Drag brakes can also work variably, so the faster you are going the more braking you get when in the dead band.
I personally turn the drag right down until the car behaves well in the dead band relative to the track conditions. Just enough to behave like a engine/compression brake in a 1:1 car.
