Yes.  The macro .DC embodies the assumption that with the vertical spacing
set to N points (.vs N), the read-only register .v = 10*N units.
But this is machine-dependent and may vary.  After corresponding with David
Wolverton, I believe that on his machine .v = 3*N, so Bruce Barnett is right:
David should be OK with an amended line:
 .nr pS (\\n(nL*\\n(.L*\\n(.v/3)+(35*\\n(fS*(3*\\n(nL-4)/200)
                              ^instead
