A 1/1 bevel means that on the base, the metal edge has a 1 degree upward bevel so that it is not come rely flush with the snow. When you put a bevel on the base edge, you still usually want a 90 degree edge so you typically match the base bevel on your side edge so if the base is 1 degree, you match it with a 1 degree side edge bevel.
Park boards often come from the factory with a 2 or 2 1/2 degree bevel to make them less prone to edge catches on features. Even with a park bevel, you really want to maintain a 90 degree edge so the side bevel is also 2 or 2 1/2 respectively.
Sometimes the side edge bevel is expressed in terms as it relates to the boards base so it will be 90, 89 or 88 degrees.
Some beginner boards have a 3/3 bevel to make them even more catch free. They are great for what they are designed for and for park, but suck for aggressive riding on firm snow.
While all this is true, detuning the tip and tail up to the contact points does help with that twitchy feeling on a lot of boards when flatbasing or just slightly on edge. This was especially true back in the camber days. I detuned the tip and tail on my NS and it does feel smoother when bombing, while leaving the base and side bevels stock past the contact points.
