I got the Amex Surpass this year and put $40K spend. I went over the $40K a week after my statement closed in Dec. Amex reports to Hilton the spend 48 hours after the statement closes that contains passing the spend threshold (I.e. Jan). So I have Diamond status until Mar 2018. I earned 195804 points on the $40K spend and spent $205 on fees for MS ($280 inc Surpass fee). I probably won't be able to do this again since Amex closed my Serve account this month.
