Could you clarify if you mean 5 turns through each core as in separate chokes in series. Or 5 turns through both cores as in 1 choke with two cores? Or is there a difference? It doesn't seem like there would be a difference.

The number of turns (and to to the extent that it affects capacitance, wire size and spacing) sets the resonant frequency. The Fair-Rite data is most likely for small diameter wire. If you want the choke to be effective where 5 turns puts it, yes, two chokes in series would be the way to get there.
