Why don't the # of surveys finished in Respondent Funnel match the number of responses in my dashboa

My Survey Dashboard, using the same parameters: This quarter for the same survey. 2 days ago the number of responses in my dashboard for my survey said 60 and the number of surveys completed in Respondent Funnel said 65. Then, today the number of responses in the Survey Dashboard is 70 and the number in the Respondent Funnel is 65.
