I think you have the equation wrong. You have to multiply by how many tags are available in the 25% pool. Not the entire hunt. Also, if you are a non-resident, and don't have enough points to draw in the 75% pool, don't count on there being any tags left for non-residents in the 25% pool. Basically, what I'm saying is, multiply your final number by zero, and that is the chance you have to draw
