From what I remember about the book, the dinosaur motion-tracking system was programmed to only find N dinosaurs each day because there was no reason for there to be more dinosaurs.

When writing shows like Star Trek, writers often put things like Insert Technobabble Here into the first draft of the script, and it gets filled in with Reverse Tachyon Inductors later. This works for SciFi, since any explanation can be RetConned. But its glaringly obvious when done with real tech. The tech terms and snippets are more than just buzzwords dropped into a middle of the sentence. They are clearly defined plot devices with real world meaning.
