Replying to 2014 Chronics mounted wrong?

The tech at the shop mounted my bindings 1 cm in front of the center line that Line has marked on the ski.

He measured the ski and said that "true" center measured out to be about 4 cm in front of the center line that is marked. He then told me if I want to be a bit more balanced on rails and boxes that they should be mounted in front of the line that is marked.

I'm gonna hit rails and boxes but I also want to be able to shred outside the park.

Did he fuck up the mount?
