What are you using to measure after sharpening?
Side angle is difficult to measure more difficult to measure. If you use the correct side bevel angle toolyou should good. wheteher you are at 2.75 or 3.25 on the side edge is not as critical as long as it is consistent.
Base edge on the other hand is critical that you not be over or under beveled.
Base bevel is pretty easy to measure.. When you lay your true bar across the ski and tip it to match the bevel of the edge(no light showing through between the true bar and edge) you should have 1mm of gap at 60mm from the edge.with a 1 degree base bevel. .5 would be 1/2 degree .75 would be 3/4 degree. You get pretty good at eyballing it by just using your true bar to look at the base edge bevel with a light source back behind the true bar. You are also looking to see that it is consistent along the length of the ski this is critical to the on snow performance.
