The campaign options have been changed a bit for the next release. Here’s how the Select Campaign Screen now looks, with a ‘More Options’ button and a few other changes.
Here you can see the Spies and Fog of War options have been moved to the ‘More Options’ screen, and there’s another option called ‘Voter Detail’.
The Voter Detail option allows you to set the detail for the electorate, from a value of 500 to 10,000. At a setting of 10,000 (most detail), the electorate for a given region is modeled to the 1/10,000th, or 0.01%. The least detail, 500, means the electorate is modeled to the 1/500th, or 0.2%. The default is 1,000, or 0.1%,
So, at 1,000, you can have % movements of 0.1% for candidates for a given region, and the electorate for a given region is broken up into 1,000 different virtual persons (each representing 1/1,000th of the electorate). This should be adequate for most purposes, but if having that extra decimal point matters to the political wonk purist in you, you can knock yourself out.
