What you select on those forms is not set in concrete. The preferences between DFR and FSP aren't quite on the same page, so whatever happens at FSP will trump anything you've put down in the past. Like JBWings said it is a 5-1 score on which service/s you most prefer and he is right in what he said about what each score means.
It will all be explained on day 1 of FSP and you'll be able to change your preferences anytime up until OSB on the last day, even then the first question asked will be "These are your preferences, do you wish to change them?"
Hope this helps!
