You haven't defined "best". And I'm very skeptical you can do so in such a
way that Borda is best. Without strategy, Score is better than Borda. With
strategy, Borda is one of the worst possible systems; worse even than
plurality or random ballot, as with simple first-order strategy Borda
guarantees a nonentity will win. Your "restricted" Borda, insofar as I
understand it, is slightly better than that worst case, but only by means
of taking the edge off the system and making it more like plurality. Yech.

Using actual votes ignores system-specific strategy, which is Borda's worst
defect (though not the only one.)
