DD encashed does not even guarantee the PER, though you usually get it. Anyway, it is a payment for them to consider your application, not your visa. You will later pay the RPRF fee, which is for your visa, and which they refund if you do not land, or if they deny you the visa.
Look at others in the FSWP 2014 Spreadsheet: http://tinyurl.com/FSW14-Spreadsheet -> once others before you get PER, you can expect yours
