For the rest of the council, I think electing them using Sculze-STV
with the restriction that only results where the President and VP are
members are allowed would give better proportionality.

My understanding of how the ranking system works is

1) Elect Schulze winner
2) Elect 2 member council with Schulze-STV subject to winner in 1) being present
3) Elect 3 member council with Schulze-STV subject to winners in 1,2)
being present
4) Continue with process until all seats filled.  One new member is
elected to council in each step.

So, the process would be modified to

1) Elect Schulze winner as President
2) Elect Schulze 2nd place candidate as VP
3) Elect 8 member council subject to President and VP being members

This gets Centerist President and VP and also maximises
proportionality.  It also assumes all the other councilors are equal
in standing.
