Votes inside a post look like this:
##vote 1 A; B, C; D 2 Plan Tran Bonus C
Votes must be in bold, must contain no blank lines, may not lie inside quotes, and must not be followed by bold text without a blank line or non-bold text in between them. Options omitted from a question are treated as if ranked below the options that are included. Questions that are omitted from a vote indicate that the voter has no preferences for that question.
For question 1, the example voter:
For question 2, the voter prefers "Plan Tran" over anything else
For question "Bonus", the voter prefers C over anything else
If a post contains multiple votes, only the last is considered. If a voter makes multiple votes in different posts, only the most recently given preferences for each question are considered.
Although the format supports voting for multiple options with the same level of preference, this should not be confused with voting for a combination as a single option that might win monolithically. In other words, a vote for "A, B" is not a vote to do both A and B, it is a vote to do either A or B. To vote for a combination, voters should create write-ins, or use singular option names like "A+B", which have no special meaning.
Voters favoring an option that is similar to other options should consider taking advantage of the format to vote for the similar options in addition to but at a lower preference rank than their favored option. This increases the chance that something like their desired option will win, without weakening their vote for their desired option.
Although option names may be arbitrarily long, the following conventions are recommended:
Avoid long option names. The longer they are, the more likely someone will make typos while entering them, requiring manual cleanup if their vote is to be properly counted.
Write-ins of more than a few words should not be written as options directly. Instead, the author of a write-in should describe their plan in prose of whatever length, and give it a short, unique option name such as "Plan Tran". The write-in author and any other voters so inclined may then vote for it using the short name.
Launch the GUI by running the executable named "votescrape-gui". On Windows, this is located inside the "bin" folder.
The main window is what opens when you start the program. It consists of a "Scrape" tab, used for scraping posts directly from a thread, and a "File" tab, used for counting votes stored in a text file on your computer. Whichever tab is selected, pressing the "Count" button will open a results window. Counts may be performed simultaneously.
#link at the post's bottom-left and copying the URI it links to.
You can use this tab to count votes in a plain textfile instead of from a thread.
Votes in a text file need different formatting:
##vote, votes must start with the poster's name
Whenever you begin a count, a results window opens. A spinner will be displayed over the window until the count is complete. You can close the window at any time to cancel the count.
If you're scraping from a thread and the count is taking a very long time, it's possible that SA has dropped one or more HTTP requests. This can happen if you're scraping or viewing a lot of pages in a short period of time, or if you're just unlucky. Cancel the count and try again. If the problem recurs, try letting it cool down for a few minutes. If this happens to you frequently when you're not scraping or viewing large numbers of pages, please report a bug.
Each line contains a question name followed by a ranking of the options in a format similar to votes. For example, "A; B, C; D" indicates that A won the vote, B and C are tied for second, and D comes third.
For each question, these charts convey how many people prefer an option to any other option. This is the distilled data that is used to actually compute vote winners. Each cell indicates the number of voters that prefer the option whose row the cell lies in over the option whose column the cell lies in.
Unlike first-past-the-post, preference-based voting does not allow for a simple scalar metric of how close two options were. Use these charts if necessary to judge the exact relative degree of support for different options. Note that the option with the largest number of preferences over other options is not necessarily the winner, because, for example, it may be disfavored by a similarly large number of voters who are not otherwise in agreement.
The unprocessed votes scraped from a thread or file are displayed here. Use this tab to double-check that votes were counted correctly. If you need to make corrections such as fixing voter typos or adding missing votes, you can copy the scraped votes into a text file, make any changes, and then count the votes directly from the text file using the "File" tab of the main window.
Votes are weighed using the Schulze method. This method works by considering how many voters prefer any given option over any other, and selecting the option that, directly or indirectly, is most preferred and least disliked compared to the others. Rankings of non-winning options are produced by removing the winning option from consideration and re-evaluating all votes.
By allowing voters to express more than one preference and counting their votes in this manner, we encourage voters to select options more true to their preferences. For example, if a voter perceives an undesirable option A winning and a merely tolerable option B in second place, first-past-the-post voting would force them to vote for the merely tolerable option, instead of a third option C that they greatly prefer but perceive as unlikely to win. With a preference-based voting method such as the Schulze method, the voter can express his true preference for C without sacrificing their ability to support B in favor of A. This remains true no matter how many or how few other voters are making use of the opportunity to express complex preferences.
The Schulze method satisfies the Condorcet criterion, which requires that if an option would win a vote individually against every other option it must win the full vote. A corollary to this is that if all voters place votes for a single option, the same winner will be selected by the Schulze method as would be selected by a simple plurality method. This means that the counting utility may be applied to votes for which selection of winner by plurality is desired.
