Great information from Stick. Minor point, you can use only part of any bit by cutting the thickness so it fits the portion of the bit you're using, and also by how high you set the bit.
Although I am also a visual thinker, I find it hard to visualize the profile it cuts from looking at the bit. To deal with this, I keep the profile drawing that comes with the bit, with the bit. When cutting small trim profiles, I always cut far more than what I'll ultimately need because things happen, cut a miter the wrong way, cut too short, find a knot, cause a ding. Extra stock saves you bacon.
