Our expert says:
I'd increase the speed, though in practice, it probably makes little difference. That is, the difference between a faster week at a lower grade and a slower walk at a higher grade is probably too small to really notice.
Practically though, very high gradients are problematic because they become too "static", whereas moderate to small grades allow a better movement, and I think that has benefits.
So my advice is to keep the gradient in what is a comfortable range. There comes a point where the gradient gets too steep to even walk normally, and that's too much. You'll find that you are doubled over, that you're off balance, and feeling more like you're doing squats than actually walking. So find that gradient, and then increase the speed at that grade because that increases intensity most effectively.
