I've been grappling with the maths involved in adding small numbers into the equation for PR-STV (if anyone wants to help me out...). Obviously additional votes increase the quota to be elected, which therefore reduces the transfer value, but at the same time, they increase the surplus, increasing the transfer value. I'm trying to figure out if the increase to transfer value is greater or lesser than (or evern the same as) the decrease to transfer value. In short... does an additional vote going onto the Liberal pile have the value of a vote, or just some fraction of the vote. The change in transfer value will affect all the votes spilling down to lower-order candidates, but I'm not sure what affect it has overall...
Can you put up/link to the relevant numbers at present?
I think the answer to your question, if I understand it correctly, depends on the relative proportion of Liberal votes that have yet to be added (compared to the existing proportion of Liberal votes as a fraction of all votes cast).
