I'm sorry - Hare Quota?
eg;
200 voters, 3 candidates to be elected (x stands for "the rest of the
field");
69 A>B>C
69 D>B>C
29 B>x>C
33 C>x
The Hare quota is 68 (Droop Quota 51). A and D get the quota, their votes
are redistributed at fractional transfer values - B now has 31 and C has 33.
C is elected. (a droop quota would elect A,B,D)
The C voters have secured one third of the seats in the legislature, even
though 83.5% of the voters ranked C dead last. If it was a highest average
count, and A,B,D had joined together as a single party, then ABD would get
elected in a d'hondt count, as well as saint lague (specifically designed to
help smaller parties) and modified saint lague. Hare is the absolute worst
way to distribute seats (and there are much worse examples with more
candidates). You seem to be determined to sabotage the only decent
electoral system you advocate.
