I'm not sure if I understand what you're asking exactly, but I'll attempt an answer anyway:
Most perimeter oriented positions (and least inside oriented)
1. PG
2. SG
3. SF
4. PF
5. C
The list is reversed for the most inside oriented positions.
That makes PF the 4th most perimeter oriented position, and C the 5th most one (i.e the least perimeter oriented one).
