Success Path Analyzer: Skip Stages

Hello Marketo Nation!

I'm new to the Success Path Analyzer - set it up for the first time in late January and am loving all the great data it's starting to provide. One question has surfaced - if a lead moves from one of our stages to another in a single day (i.e.: marketing lead to sales lead or SQL to opportunity) - will they be counted in the Conversion Rate and outflow for that stage? Or does a person have to be in each stage for a full day in order to be counted as part of that Revenue Stage? 

Many thanks in advance!
