Droop is not better than Hagenbach-Bischoff!!! 

Okay suppose we have an instant runoff election, where we have 50 votes with Party-A as first preference and Party-B as second preference. We also have 50 votes with Party-B as first preference and Party-A as second preference.

Using the Hagenbach-Bischoff quota of 50, both parties reach quota, and there is a tie.

Using the Droop Quota of 51, neither party reaches the quota, but as they have the same number of first preference votes, neither can be eliminated; and we have a tie anyway.

So using the Droop Quota does not eliminate ties. It is a much more ugly formula, and has the property that parties with majority support, can recieve a minority of seats.

Can anybody give me a good reason why the world is still using the Droop Quota!
