We had a fairly similar grading program in my IT capstone project. The professor made it clear that if a group had either a total grifter or was an all-star team exceptions could be made. We had to give lots of presentations and question and answer sessions. It was generally pretty clear to the entire class which students were slackers and couldn't answer questions and which ones knew their stuff.
