My flood is also very uneven. I had a neighbor with a laser leveler. The secret is to concentrate on having a level line where you are going to cut. We used his level to draw a nice straight level line and cut out the drywall. Hope this helps.
right on. The system is built so that you work your way down from the cut. The 3in gap at the bottom helps a lot, because you dont have to worry about meeting the floor. The board kind of "floats" above the floor, and the gap is hidden by the baseboard. Laser level is the way to go!
