Your put in sections by what fed you fly in ,but as some say fanciers move Feds for what ever reason ,so it's at snfc committee descretion what Sections those are put in ,I know the snrpc made a rule that because of all the so called moving around to suit started ,that you stay in the same section you were in prior to 2004 ,unless you move your loft then the committee puts you in relevant section .
