In arm planning to work on mine soon. In planning, one post and the Reflrctix site suggest that the R factor increases when allowing for space between it and wall. If that is the case I would think it might be very effective on the back of the doors and wall, as well as the hot spots you have already hit...assuming you aren't opening the doors frequently.
From what I read Reflectix impact against the wall is R3. When space is allowed up to R21. Either way I plan to hit the areas you did and if possible the doors.
