I'm not discrediting it; I'm actually agreeing with what you just said. It would take a very large piece of polycarbonate to make a good target for weight savings, and then you need to put lots of holes in it to make a difference. If you have large metal pieces on your robot (sprockets, plates, mounts), you can get more weight savings with fewer, or smaller, holes. I've seen several teams (including mine, four years ago) drill a bunch of holes, get reweighed, and find that they hardly made a difference.
