This will give us proportional shares. Droop and Imperiali quotas are different - odd like peculiar. The people who use Droop will divide by ten plus one to give us eleven containers for votes but because only ten are to be elected one container of votes is wasted. The reason given to use the Droop Quota is to help assure that a majority of the voters will be able to elect a majority of the council members. A fifty percent voting bloc would be able to elect six members to a council of eleven seats if the Droop Quota is used.
Droop favors the larger voting blocs.
The rational is that the largest bloc should be allowed to govern. The Imperiali Quota will divide by ten plus two. Droop and Imperiali will both take some representation away from the smaller parties and gives it to the larger parties. I feel that a true, unbiased proportionalist should favor the Hare Quota. Living in Cambridge MA gives me a bit of an advantage in this regard, since we can illustrate with real data and experience that it is the case that ideological slates and constituencies of higher socioeconomic status receive an advantage with the Droop Quota.
