I was actually hoping you had an overall of what's there. Not the print Being a finish carpenter, I'm not real quick to let plumbers slide, but in this case, maybe. If they planned for a 32" base on one side, and a 36" base on the other side of the cook top base, and they got switched by a speed demon trying to get it done, there's a 4" shift in the placement of the cook top base and 0" in the overall run. It's easy to forget how works in the real world. These guys are working on a schedule. They do this every day, unlike Joe homeowner who measures fourteen times, posts questions to a forum, and then sands his shims to get it just right. Doesn't make them hacks.
