I think there might be a benefit in some situations on having a bit of extra down pressure, beyond just the weight of the SB.
I will however warn you that you might want to limit the upward lift to 4", as the higher you go, the more prone you are to tossing the belt. These belts do not last long that way and can be a real PITA to mess with in the cold, especially if you have to change one.
