Just adjust the sliders. The cat tells you the damage. This probably isn't very accurate, but it's the best I could do. To explain why there are 6 levels of weakness and not 3, It's because some Pokemon just are that way. For example, A grass type Pokemon like Sceptile is weak to fire, and a steel type Pokemon like Klink is weak to fire. But a grass and steel dual type Pokemon like Therrothorn is double weak to fire because it's grass and steel, both of which are weak to fire.
