There are bunch of things that confuse me in this post, but the 2011 Worldcon was in Reno. It was the 2010 Worldcon that was in Australia.
You can find the voting statistics for 2010 at http://web.archive.org/web/20100917163329/http://aussiecon4.org.au/hugoawards/files/2010HugoVotingReport.pdf. (The Aussiecon 4 web site has been taken down, but it was archived.)
The WSFS Constitution (section 3.11.4) requires a Worldcon to publish nomination statistics "including in each category the vote counts for at least the fifteen highest vote-getters and any other candidate receiving a number of votes equal to at least five percent (5%) of the nomination ballots cast in that category, but not including any candidate receiving fewer than five votes." So the number of works that get listed as runners-up for nominations in the Hugo statistics will vary slightly from year to year, but will also depend on how much work the Hugo administrators want to do in publishing the list.
For example, there were 1,827 nomination ballots submitted for Best Novel this year. If the administrators wanted to publish only the nomination count for the top 15 novels and any other novel receiving at least 5% (that is, at least 91 nomination votes), they could do that. Or they could go deeper down the list, and publish the nomination counts for all novels receiving at least 0.3% of the nomination votes (that is, at least 5 nomination votes). Or they could go somewhere in between.
But, in any event, they have already revealed that 587 different novels were listed on those 1,827 ballots. (See https://chaoshorizon.wordpress.com/2015/04/06/how-many-puppy-votes-breaking-down-the-hugo-math/.) Many of them were probably listed by only one to four people and thus will not be listed in the final statistics in any event.
In summary, I'm not sure that the data you are using supports the conclusion you are trying to draw from it.
