<prompt> Human: I just moved cities and had to float a much bigger amount on my credit card 18k for about 25 days before I could pay off from reimbursed expenses.I normally only keep 2k - 5k on my card, so this is a massive change. At the same time I payed it off in full at the end of the month.My FICO score dropped from 805 to 784 as a result.How long will it take to repair this damage to my score?  <response>: A month.
