I have coarse, dense, highly porous bra strap length hair. I apply my products then I scrunch squeeze out excess moisture with a t-shirt of MF towel. Then I diffuse for seven to ten minutes. Not all the way dry. I don't have the patience. And I find stopping earlier is better for my hair overall. Less frizz.
Oh and maybe 70-80% dry. Also depends on which products I'm using. Certain ones dry faster.
