The cutoff score is determined by the number of invitations that were issued, not the other way around. They start with the person with the highest score and issue invitations in descending order until they reach the last invitation. Lots of people will have the same cutoff score, so at that point they then switch to ranking by seniority-- i.e., older profiles get priority-- which determines the cutoff date. The cutoff date only applies to people with the same score as the cutoff score, such that if the cutoff score is 451, all candidates with 452+ will receive an invitation; those candidates with a score of exactly 451 will receive an invitation if their profiles were made before or on the cutoff date/time.
