To continue, both the forklfit and the load are vying for maximum stability, however, we both know neither should get it. There must be a compromise, giving reasonable stability to the forklift, and its load.

If the forks are tilted slightly back, the load is sitting on a slight angle, resting against the load backrest, comfortably, and the center of gravity inside the stability triangle is not forced into the narrows of the triangle, hence, slightly tilted back. As mentioned, 2-3" at the heels and 4-6" at the tips is considered slightly tilted back, and since no operator will get out the truck and measure, the figures can be used as a reference.
