Dear James,

I try a very succint summary...

SPPA is fully proportional, and it uses a rallying method to cope with
vote-splitting issues.  I wanted to be able to put all candidates of a
same party in competition in an open list. But other methods let only some run
in the same electorate district (STV) or use huge list of candidates which can
discourage the voter (Brazilian method?).  I tried to define equivalent
in every districts so the results can be compared between districts to select
the elected representatives of each party.  Finally I added an option to
avoid the possible instability that fully proportional model can introduce.

The stuff left is mathematical mechanics...
