It depends on the razor. In a perfect world the bevel would be the same width on both sides the entire length of the blade. But because of slight imperfections that normally doesn't happen...especially if the blade is warped.
It's not that important to have even bevels as long as both sides meet at a sharp point.
If you are using a microscope you should be able to see what's going on and in your case (new unhoned razor) it might be a little easier if you coated the bevel with a magic marker...that way you could see if the metal you're honing off is going all the way to the edge or not. Using a scope is an art of it's own so be sure to vary the angle of the light source (I use a pen light) until you have an optimum image.
