It is installed the best way:
"Even tiny voids can cause heat loss, because they allow air to move around inside the stud cavity. If a batt is stapled to the sides of the studs, crushed or cut short, air can rise up the warm side of the cavity and fall down the cool side. Heat rides on this convective loop, actually traveling around the insulation."
I would pull some out to make sure you have a continuous air flow, 1-2", or more on low sloped roof, to remove the moist conditioned air leaking from in the room. Soffit and ridge vents are equally important. Use a vapor barrier paint primer as well.
Be safe, Gary
Clothes taking longer to dry?
Clean the dryer screen in HOT water if using fabric softener sheets.
They leave a residue that impedes air-flow, costing you money.
