If one has a partitioned bobbin, say 7 sections.
How would one wind the primaries and secondaries?

The secondary would be many parallel turns to get to the current capability.
So all these parallel turns need to be present in all sections?
The primary will probably be a few parallel turns. Again do all these turns need to be present in all sections?

No again 🙂
All is in series,for more current use thicker wire.Can be Litz-wire.
All turns should be present in all sections if use hard swithing.But if your secondary have 2 turns,it can be in 2 sections,not in 3.

OK,
I think I get it.
The whole primary must be in one long winding.
The sections contain a part of that long winding.
All the current in the primary winding MUST pass through each section.
Similarly, the whole secondary is considered as one long winding.
The current in that long winding MUST pass through each section.
The alternative that I was thinking about was for a secondary that required 6parallel wires and a total of 26Turns was:
2 wires and 26T in section one,
2 wires and 26T in section two,
2 wires and 26T in section three.
Parallel the three sections to give 6wires and 26Turns.
If I now understand correctly, this is not an acceptable way of interleaving the secondary winding.

Yes,this is much better.But you should wind:
Prim
Sec
Prim
Sec
....
And not:
Prim
Prim
Sec
Sec
....
And you can use 26T with 6 wires,all in series.
Or you can cut separators 🙂
