Advanced Option - Preserve last x sentences

In 2009, contentboss announced an extension to jetspinner syntax. This extension allows you to specify an additional 'randomizing' percentage in your jetspinner syntax. What this does is randomly omit sentences each time the syntax is spun, which results in far more variation between copies of the spun article. This particular box allows you to specify how many of the ending sentences should be preserved (i.e. should always be present, even if randomizing is being used). This is so if your last sentence, for example, is particularly important (such as a conclusion), you don't lose it in the randomizing process.
