If you notice it's not cutting straight then apply more pressure to the side needed so it's nice and straight but for the secondary bevel if you wish to make one it only has to be less than a mm in width just barely visibly to the eye. Here you will make a few light strokes and on your highest grits a few more very light ones and your done.

I sharpen all my chisels using the MKII and not one of them has a crooked angle it only takes practice. I first practiced on some cheap stanley ones before I moved to my good ones.
the perfectly repeated angle of the microbevel across various chisels and plane blades leads me to believe that is is not user-, but jig-caused

however, as i said previously - it's also immaterial...
