If your concern is that the same GP appears 2 times in a row, I can assure you that's perfectly normal. Each time a new GP is generated, it's chosen randomly from the database. Given 307 GPs, the probability of getting the same GP as the one before is 1/307 (0,33%) *. There used to be much fewer GPs, so the probability used to be nearly 1%. If you've hunted thousands of GPs (like me), you've seen this happen dozens of times.
