Values of ﹩{\dot{M}}_{2}/{\dot{M}}_{1}﹩, ﹩{\dot{J}}_{g}/\dot{M}﹩, and ﹩\dot{J}/\dot{M}﹩ from q = 0.01 to q = 1 with ﹩{ \mathcal M }=10﹩ and disks with viscosities ν = 0.001, ν = 0.0005, and α = 0.1, averaged in time over the last 500 orbits of each simulation. At all mass ratios below 1, we find that binaries accreting from α -viscous disks accrete more preferentially onto the secondary than those accreting from constant-ν disks. Depending on the viscosity prescription, binaries at intermediate mass ratios, 0.05 ≲ q ≲ 0.2, experience negative gravitational torques, which we discuss further in Section 3.2.2. Numerical values are provided in Table 4.
